BitTorrent Bleep expands the Bittorent protocol to enable people to make voice calls and send messages over the Internet without using a central server to direct traffic. Users will find one another through groups of other users, with no records of the calls or texts stored anywhere along the way. Once a connection is made for a call or text, the communication travels directly between the two computers involved. That peer-to-peer approach also defies mass surveillance.
BT Bleep is currently invitation only and limited to Windows 7 and 8.
