For questions pertaining to Peer-2-Peer (p2p) protocols and applications.

Peer-2-Peer is a network load distribution scheme where users are passing network traffic to each other ("peer to peer") instead all users connecting to a server. This has advantages of alleviating network congestion at bottlenecks, and has a special benefit in file sharing schemes where the server holding the file could be down, but enough users have enough pieces of a file to collectively have the entire file available.
