Tribler - file sharing client for Internet TV

From the site, software for video file sharing that has a basic understanding of human friendships, of user tastes in content, and of Internet connectivity between users. Tribler is based on Bittorrent. The Bittorrent protocol designed by Bram Cohen works great and currently dominates the traffic on the Internet backbone, but it lacks many features that may be very useful. We are improving this protocol with over a dozen people with such features which go way beyond the original. We are extending the code from the ABC project. Note that we are not officially connected with the original author of Bittorrent.
Integrated keyword search (torrents, youtube, liveleak) & browse for newest content, most popular, recommended and much more. Fast downloading, play while downloading, integrated video player.
The name Tribler stems from the word Tribe, referring to the usage of social networks in this P2P client. The first version of Tribler was a small enhancement on the ABC (Yet Another BitTorrent Client), leaked out on the web on February 26, 2006.
