We all know that while bittorrent is "peer to peer" it still relies on trackers, directories, etc. Seems that what claims to be a Truly Decentralized BitTorrent Downloading Has Finally Arrived.
BitTorrent is a great technology to share files both quickly and efficiently, but like most other P2P-technologies it has an Achilles' heel. The download process relies in part on central servers that can crash or go offline for a variety of reasons. To address this vulnerability the first truly decentralized BitTorrent/P2P client has been developed, meaning that no central trackers, or even BitTorrent search engines are required to download movies, software and music.
And later on in the article on why this is different that Kazaa, Limewire, etc:
Many readers wonder why this is new compared to Kazaa, Exeem, LimeWire, Gnutella, eMule. Well, that explanation is a bit technical, here it goes. All these client either contain spam or use servers. For instance, Limewire Cooperation was sending out digitally signed instructions to block anti-piracy companies and spammers in general (157 pages of details).
Great stuff from torrentfreak.
