Does anyone know Connect Hosts that are not on the gate 6346?

I am using a local universitary network that has recently banned all the gates to Kazaa, napster, gnutella etc, so we are desperately looking for alternatives...

I am just a simple college kid and am not al computer-know-it-all, so some simple human language in any answer would be much appreciated ;-)

ps: if it is of any help, I am using Macphex 0,7,3 on an iMAC with mac OS X 10,5,1

Thx!
