A Lan P2P for college students
 

As some students may know Colleges have been blocking p2p and things like that. There are some ways around that but I'm searching for something different. I'm looking for a program that only allows you to download from other people on you LAN. I know there is a program like this out there but I forgot the name of it. I tried searching google but had no luck. Anyone know what I am talking about?

The only one that I know people used a lot was DC++
