Want to send large files, without the whole world catching on? BitTorrent's going the DropBox route, with the launch of the simply -- and friendly -- named Share, a desktop app that allows you to transfer HD movies, photo collections, et al. by dragging and dropping files. The service, which is built on top of BitTorrent's much loved technology, doesn't impose any size limits and stores the content in the cloud, so you can share with offline users. Share also lets you set groups for transfers, so the rest of the world doesn't get a crack at your files. And, because you can't launch a service without some manner of social functionality these days, the aforementioned recipients can comment on the transferred files, Facebook-style. No word yet on any plans for boy band tie-ins.
