Well, Bittorrent requires the use of servers called trackers (not to be confused with the sites that are also called trackers, list the number of seeders and leechers, and allow download of torrent files) that keep track of seeders and leechers and tell the individual instances of Bittorrent where to get and send bits of data from and to. If they shut all of these down (pretty difficult task considering how many trackers are foreign), BT is pretty much done. Some torrent files are hard enough to find as it is. :/

The RIAA is pretty powerful and they've raised a big stink about P2P programs before. The MPAA also has a bone to pick with BT, what with the popularity of pirated movie downloads. Those two together spell serious trouble for BT.
