Tribler is a new, free/open source P2P network designed by Dutch academics to provide greater scalability and relevance to BitTorrent-style networks. Tribler defaults to sharing among your friends (and discovers new friends based on who's sharing stuff like the stuff you like), donates bandwidth to your friends, and so accelerates downloads. Tribler's authors present their technology as a means of delivering high-bandwidth material, like HD video, over the Internet, with a recommender engine that helps you find the stuff you don't know you're looking for.
