Anyone knows of a good P2p program?

Always use BitTorrent if you can find a torrent for what you need.

eMule is the largest one and it's great for rares, old downloads no longer available in torrents, and mass downloads (downloading many files at once). It's bad for choosing one file and expecting it to be finished quickly. It works best in long sessions.
