As powerful as RSS is, having it work with BitTorrent once in awhile is sort of handy as well. BitTorrent is a powerful new way to distribute files and media that still has yet to meet its full potential. While it stands firmly on its own two feet, having it combined with RSS only works to prove that we truly are seeing the birth of changing media. Just check out these resources:

Enclosure-style
Torrentocracy
Torrentocracy is a plug in for MythTV, a “tivo-like” software package for Linux. I don’t run MythTV, so I can’t vouch for the quality of Torrentocracy, but I haven’t heard anything bad about it. If you don’t run MythTV, it’s clearly not an option.

RSS Import
RSS Import is a plug-in for Azureus . Its interface is fairly bare-bones and it seems to ignore its own parameter which specifies how often to check the RSS feeds for changes. It takes a list of feeds separated by semicolons in a small text box as the means of input, so clearly the UI could use some improvement. It supports filtering, but there’s no way to associate particular filters with individual feeds. All filters apply to all feeds. It’s also somewhat lacking in documentation. For instance, to use it you both have to set a default save directory for Azureus and tell Azureus to save torrent files and specify a directory for that. There’s no documentation to tell you that, although the RSS Import console does clue you in on the first one when you try to use it without setting that. The second one I had to puzzle out on my own, however. Despite these difficulties, it works well, begins downloads fully automatically, and does save all of your settings for both filters and feeds. This should run on all platforms on which Azureus runs.
bitTorrentIntegration.root

bitTorrentIntegration.root is a plug-in for Radio. Radio is a commercial product which I have not purchased, so I have no personal experience using this plug-in. The documentation suggests that this only runs on Windows, that it supports multiple feeds, that it does not support filtering, and that it does begin the downloads completely automatically without user intervention.
iPodder

iPodder’s main focus is on downloading audio enclosures, but the newer versions also automatically download bittorrent enclosures. I’ve tested the Windows version of this client, and I was fairly impressed with it. The interface is straightforward and everything worked fairly smoothly. It is not as feature-rich as some of clients. For instance, it does not support filters of any sort. It does have a more feature-rich scheduler than most of the clients, although it does not any way to respect the TTL (time to live) field of the actual feed. Also, the options for how frequently to check for new feeds are limited to a set of choices, rather than just allowing you to set your own time.

It also does not hang around and help seed the torrents at all, and I found that it would sometimes launch iTunes to play a Quicktime movie which seems like a definite bug. And when given a new feed, it only downloads the most recent entry. If you want older ones downloaded, you have to do it by hand. Still, because of its overall ease of use, this is the best choice for most users for enclosure-based feeds so long as they do not need filtering. This supports Windows and Macintosh (10.3 and higher). There is a Linux version in beta form.
