Last week, the MPAA declared war on TV filesharing, taking out some of the most popular BitTorrent trackers all at once. You could almost hear the cries of anguish screaming through the Internet. Well, today, the Internet is chuckling. For there is a new beta release of BitTorrent. And it removes the need for a central tracker, instead turning every client in the swarm into a mini-tracker. The weakest link in the BT design has been fixed. Oops.
