New wave of secret file sharing breaks over Web
The first is Optisoft which runs on Blubster (http://www.blubster.com) and Piolet (http://www.piolet.com), music-only file-sharing networks.

Another EarthStation 5 (http://www.es5.com) and Filetopia (http://www.filetopia.com) are also claiming that they could keep the RIAA away.
