Seeking a p2p program to run exclusively on a LAN

[klowne]

Hi, at university we have a large LAN connected to the internet through a transparent gateway. They are very strict about p2p programs (presumably due to bandwidth expenses and network slowdowns) and their standard response to detecting them is to permanently disconnect the user from the network.

Presently most people run iTunes which only shares its collection within the local network - it doesnt connect to anything outside the LAN and as a result noone gets into trouble. People then download using MyTunes. This is fine except it only works for MP3 and AAC files and the latest version has some annoying restrictions.

I was wondering if anyone could suggest a p2p program that can be run and easily set up on the computers in the LAN that will definately not connect to the internet and get anyone into trouble, lets us share anything we want and hopefully doesn't have any spyware, etc.

Thanks
