Peer-to-peer file-sharing makes up a significant chunk of Internet traffic and there’s not much that ISPs can do legally to stop that, nor should there be. In order to deal with this, AT&T has decided to create what is essentially a dedicated lane for P2P traffic such as BitTorrent that will not only speed up the transfer of data but will reduce the networking costs on AT&T’s side of things as well. A win-win by the looks of it.
