Yes, it can be done.
First, on the Mac you'll need to get a kernel extension called, "IP over FireWire".
Download it from Apple.com
Notice that it's a preview release. This little ditty isn't quite ready for prime time yet. Also, I believe you'll need to have developer's tools installed. Third, it's OS X software, not OS 9/Classic. Install the IPoFW software on any Mac you wish to network via FireWire.
Second, you'll need to know if XP can do IPoFW. If so, you're in like Flynn. If not, you're screwed unless you know how to write device drivers and/or system extsnsions for XP.
Do both your computers have ethernet? That would be the simplest way to do this. Just plug an ethernet cable between the two computers. Activate file sharing on both comptuers. Go to the GO > Connect... menu in OS X and you'll be able to connect to the PC from the Mac in the usual way.
It doesn't matter which flavor of ethernet cable you're using. It can be either a patch cable or a crossover cable. The ethernet port on the Mac will detect and switch as necessary.
If you need cross-platform sharing software for the Mac, don't bother with PC/MacLAN. Check out Thursby Software. A program called "DAVE" will allow you to network and file share between PC and Mac. Another program called "ADmitMac" will allow you to connect your Mac to an Active Director or Windows NT domain. [ 10-24-2003, 10:32 PM: Message edited by: Randy Stankey ]

White iBooks with dual USB ports and a 10/100 ethernet port can auto-configure for crossover or patch cables. As far as I know, all 10/100 ehternet controllers after that time and all 10/100/1000 ethernet controllers in the new Powerbooks do it as well. Older iMacs, iBooks or Powerbooks do not have it. However, only ONE out of two computers need to have auto-configuring ethernet for the scheme to work.
Agreed, Joe! Dave should be a last resort for use when you only have OS 9. OS X has it built in.
Also remember that "FireWire Target Disk Mode" is different from "IP Over FireWire". With Target Disk Mode, you shut down one computer and restart while holding down the letter "T" on the keyboard. This will abort the usual boot process and turn the computer into the equivalent of an external FireWire hard drive. IP Over FireWire is a set of system extensions that makes your FireWire port into the functional equivalent of a 480 Mbps ethernet port. IPoFW gives your FW port the ability to use TCP/IP, AFP, HTTP, FTP, SSH, etc. just the same as your ethernet. Be aware that this software is a PREVIEW version meant for developers to use when writing programs that will use the eventual public version later on. It's also a kind of public beta so that Apple can work out some bugs, etc. In the documentation that comes with the download it says, "Do not use for mission-critical purposes." There are also some funky tricks to getting it to work right but I expect these to be worked out when the final release comes out.
I don't think XP has IPoFW, nor do I know of software that can make it work for XP. I don't do Windows, however. I could be wrong.
Joe did give me an idea: What is there to prevent you from putting your Mac into Target Disk Mode and then plugging it into a PC. For all intents and purposes, the computer has morphed itself into an ordinary disk drive. The only thing I can think of that would hinder it is the differences in disk formats. I know that Macs can read the PC's file format (via a kernel extension) but I don't know if the PC can read the Mac's HFS+ format.
It could be worth trying. What's the worst that could happen? The drive just won't mount, no?
Part of the reason those computers show up in your "Go > Connect..." menu is that those computers were once available for sharing on your network. You might not be able to connect to them if they have "fallen off" the network or if the person who owns the computer has deactivated file sharing. Don't forget that the password could have been changed sinc you last hooke up to that computer too. There is still some funkiness in the networking system, even though Apple claims everything is working OK.
Sometimes, when I connect to the network at Mercyhurst my other computer at home will still show up on the list even though it's not really there. Sometimes, the reverse will happen after I come home at night. If I try to connect to a computer that has "fallen off" the network my system will seem to hang until it determines that it can't find the remote computer. Other times, I won't be able to connect to a computer that SHOULD be there but doesn't show up on the list. I think there is some latency in the updating of the "netinfo" database. (Is that what it's called? Whatever it is... That list of remote devices that the comptuer keeps so that it can find them again.)
To be honest, I don't really have much call for networking my Mac to the PC network. I do it occasionally and it works well ehough when I need it. It could be a little "smoother" though. Maybe I just need to study up on some details?

Windows XP is claimed to be able to do IP over 1394, but as we only have about four XP amchines, we are nearly all Windows 2000, and none of those has 1394 installed, I cannot test it yet. I should have a XP machine with 1394 in a couple of weeks or so, and I'll try it then.
Mac OS X to Windows 2000 over Ethernet works fine, I do it all the time.
Nate,
Right-click 'My Network Places', select properties, right-click the network connection you want to use, select 'Properties' of that, and check that 'File and Printer Sharing for Microsoft Networks' is in the list of installed components. If it isn't, install it, you will probably need the Windows CD to do this. If it is already installed, make sure that the check box next to it is checked, to enable it for that connection.
Before you try to get higher level protocols working, check that you have IP connectivity between the machines by opening terminal on the Mac and ping it IP address of the Windows machine. If this doesn't work, then nothing else will.
If you are just connecting the two machines together, with no DHCP server, you will probably have to mauually configure both with static IP settings. Windows machines in this situation can configure themselves using APIPA with addresses in the 169.254.0.0 network, but I don't think Macs can.
I've just remembered where there is a laptop with XP and 1394, it's locked in someones desk at the moment, but they are back in on Monday, and we have in iMac in the department for testing purposes, I'll give it a try next week.

I tried IP over 1394 this afternoon. Between two Windows XP machines it worked fine, it didn't, as I expected, get an IP address via apipa, and I had to set static addresses. Pretty fast, though not as fast as normal 1394, I suppose there's some overhead in creating IP packets, and tunneling them through 1394.
This was between a laptop and a desktop, with all other network connections disabled. Re-enabling the normal ethernet connection on the desktop, and creating a network bridge between the two ports allowed the laptop to obtain an IP address from the DHCP server, and to talk through the desktop to the rest of the network, and beyond.
I have not yet been able to test between a pc and a Mac; the Imac in the office does not have the necessary version of the software on it.
The Apple site says that IP over 1394 is built in to the 'Panther' version of the software, but not 'Jaguar'. I'm not sure which version numbers of the system these are, but I know that 'Panther' is the newest one, and we don't have it yet.
The download from the Apple site for use on older versions of the system seems to only be available to registered developers, which I am not.
If it works as well with Apple as it does with XP, then I can't see any problem with it. I will see if our Apple person has a copy of the update for the older system.
