BitTorrent: Distributed trackers

The world of BitTorrent is quickly changing. It is most likely due to the MPAA,RIAA cracking down on torrent/tracker sites. So in the open source world, innovation wins again. There are now a few BT clients out there that have augmented their already superior distributed file sharing abilities, to be able to manage almost trackerless file sharing. The new method involves using something called DHT(Distributed Hash Table) to manage who has what file. It basically turns every BT client into a mini-tracker. This way you do not need to upload a tracker to a web site. Assuming you have web access for the seed file, just about anyone can now share a popular file, without crushing their bandwidth bill.

The clients now supporting this new method, include Azureus, and a beta version of the original BitTorrent.
