Some Questions, file transers

Can I connect two computers (Win98 SE and Win XP… /me shudders) through USB or serial, etc. And transfer a couple of large files (Full ISO’s and such).

How?

I think USB networking might require some extra adaptors. But as long as you have the correct cables im sure there is software that will support it. you can do it via firewire ports, XP supports that, win 98 don’t, but you can find some 3rd party software to do it (i think firenet supports it).
