creator Bram Cohen has eliminated the need for Web site hosting of centralized servers known as "trackers" in the latest beta version of the peer-to-peer software. These servers coordinate the BitTorrent download process and have been a key resource for antipiracy units in identifying people downloading and sharing copyrighted material.
The change may cause problems in shutting down the illegal online distribution of software and content, according to the Business Software Alliance, an industry group.
"Currently, if a tracker site is shut down, many downloads are disrupted," said Tarun Sawney, BSA Asia antipiracy director. "So removing the trackers from the equation will obviously cause those of us on this side of the battle to regroup."
However, Sawney pointed out that BitTorrent files could still be identified. "BSA has traditionally sought the assistance of those hosting the actual pirated files. With or without the tracker sites, someone still hosts the infringing files," he said.
While BitTorrent's Cohen said the tracker removal feature is part of his ongoing effort to make publishing files online "painless and disruptively cheap," the move is only one of several designed to remove BitTorrent's dependence on centralized trackers.

One development effort by, the group behind the once-popular SuprNova.org, aims to decentralize the BitTorrent protocol in the style of peer-to-peer networks like Kazaa, while a similar effort to Cohen's was announced earlier this month by the developers of advanced BitTorrent client software Azuerus.
