While FTP is good you'l need webspace for this. IRC is a good idea for this actually, it allows resume, therefore you don't have to worry about getting DC. I wouldn't use MSN as suggested above, as it doesn't have resume so it's pretty risky and not a good idea for regular big file transfers. In IRC simpy setup your own channel on your own server, and dcc send each other the files, should work a treat.
