Need some good resources on developing a peer to peer file sharing application (like Gnutella, Limewire etc), but much simpler. I would prefer to use C++ and code under linux. I have some experience in socket programming - I have done a chat client/server program which connects two linux machines. For this p2p application, I would like to do a few things:
1)send files across peers
2)search for files on the p2p network

I'm thinking something small scale - say 10-100 nodes max.

I would appreciate any information on peer to peer related socket programming in C/C++ under unix. I don't want to use Java(JXTA) etc.

Thx in advance.
