Tribler - anonymous downloading

"Tribler - Privacy using our Tor-inspired onion routing. Tribler offers anonymous downloading. Bittorrent is fast, but has no privacy. We do NOT use the normal Tor network, but created a dedicated Tor-like onion routing network exclusively for torrent downloading. Tribler follows the Tor wire protocol specification and hidden services spec quite closely, but is enhanced to need no central (directory) server"

This looks very nice. And they are constantly improving.
