Kazaa files copyright complaint against RIAA, others: "The maker of the popular Kazaa peer-to-peer software has turned the tables on the Recording Industry Association of America (RIAA) and a number of entertainment companies by suing them for copyright infringement.

"Earlier this week, Sharman Networks Ltd., the company that distributes the Kazaa Media Desktop software, accused the RIAA and several entertainment companies of violating its copyrights by downloading an unauthorized version of the Kazaa file-sharing software and using it to hunt down the IP (Internet Protocol) addresses of alleged music downloaders."
