Announcing the second alpha release of iTorrent. iTorrent allows you to download BitTorrent podcasts from iTunes. It transforms BitTorrent podcasts so that you can update them just like any other podcast in iTunes. Details can be found at http://www.itorrent.cc.
With its second alpha release, iTorrent still isn't pretty, but it is much easier to install and run.
Technical Details: iTorrent runs as an RSS proxy on your local machine and will fetch enclosures from a BitTorrent network on behalf of iTunes. The BitTorrent content will then be fed to iTunes via a standard HTTP loopback connection.
