Nerval's Lobster writes "BitTorrent Sync has reached its Beta milestone. The tool, which allows for secure file-syncing between devices, has been under development for quite some time: BitTorrent released a limited pre-Alpha program in January, planning to use any feedback to refine the software before release. Key features include the use of peer-to-peer technology for direct synchronization, rather than storing files in the cloud—a key differentiator from similar storage services on the market. 'It fits into our overall goal of making a better Internet using P2P,' BitTorrent Inc. told TorrentFreak when that pre-Alpha rolled out. In the intervening months, of course, former federal contractor Edward Snowden leaked a variety of top-secret documents about NSA surveillance to The Guardian, kicking off several weeks' worth of discussions and handwringing over government snooping. Several of those documents suggested that an NSA program codenamed PRISM siphoned user data from nine major technology companies, including Google and Microsoft; the named companies have stridently denied any involvement. Those revelations about the NSA—even if totally unsurprising to the paranoid—could kick off renewed interest in software tools capable of securing data against prying eyes. In other words, this could be just the moment for something like BitTorrent Sync to hit the market. 'Sync is a response to what we see as real, fundamental challenges to personal data movement: the limitations on speed, size, space, privacy, and security that come with cloud dependency,' read a July 17 note on the BitTorrent Blog."
