In what is perhaps the most comprehensive study of file-sharing traffic ever conducted, British measuring company CacheLogic has determined that the music industry's legislative attack of P2P users has failed. While use of KaZaA, which is the primary battleground of the industry's lawsuits, has dropped, file-sharers have been displaced but not dissuaded. Bit Torrent was the source of 53 percent of P2P traffic, according to CacheLogic.

"The overall level of file sharing has increased," said Andrew Parker, CacheLogic's founder and chief technology officer. "Users have migrated from Kazaa onto BitTorrent."

The study was conducted over six months, using high-volume packet-sniffing technology installed at nine top-level ISPs around the world. The science behind this work makes the biased "studies" periodically emitted from the RIAA, IFPI, and MPAA look like children's school projects. CacheLogic is hoping to sell its measuring technology to ISPs later this year.
