European company known as AllPeers has released a beta version of a new Firefox extension (download) that promises secure and snoop-free peer-to-peer file sharing. Unlike traditional file sharing systems, the extension is designed for individuals and small groups of users-e.g. friends, family, and colleagues. It uses BitTorrent to power its back-end and encrypts all communications with the Secure Socket Layer protocol. Since the system is decentralized and doesn't allow uninvited parties to snoop into private networks, file sharing happens in an effective "darknet" where communications and data transfers are kept entirely private. AllPeers provides a tour of its software, and the extension itself can be downloaded from Mozilla's Firefox Add-ons website.
