Windows/Mac/Linux: BitTorrent is an efficient way to quickly share and download files, but with organisations cracking down on file sharing, you may want to keep it more private. OneSwarm is a web-based BitTorrent client designed to share files privately between you and your friends.OneSwarm keeps your file sharing traffic private by routing it through a number of different people within the OneSwarm service, so you never know where the source file is coming from, nor does the file originator know who's downloading. You can connect to your real-life friends by importing your GTalk contacts or adding them manually, as well as connect to other OneSwarm users on their community server. Plus, not only will OneSwarm download files for you, but it can also convert them to Flash video on-the-fly for streaming, so you don't even need to finish the download before you start watching a video.
OneSwarm also does regular public BitTorrent transfers, but the data doesn't go through OneSwarm's anonymous transfer process; it just works just like any other BitTorrent client. Check out the video to see more about how OneSwarm works, and hit the link below to check it out.
OneSwarm is a free download for Windows, Mac OS X, and Linux.
