So, Azureus is great but a) It uses Java... not bad but an extra step for downloading, and b) it's complex. It takes a guy like me making a video about how to get it working with RSS. Not at all intuitive.
uTorrent was suggested (www.utorrent.com). Problem is it doesn't work with RSS 2.0. From the FAQ:
-----
Does µTorrent support RSS feeds? Yes, as of 1.3.1 beta build 374. RSS 2.0 support is incomplete: most RSS 2.0 feeds will not work. It does not support RSS feeds that use RDF. It supports links in <guid>, <link>, and <enclosure url>. It will NOT auto-download for feeds that link to HTML pages instead of the torrent (such as Mininova)! However, you may be able to use the MiniRSS feed fixer script to modify some feeds to work with µTorrent.

nimiq is another one (www.nimiq.com) but it does not share files. It only leeches them.
So the requirements are: Windows, No Java, Simple, Full BitTorrent, RSS enclosure support
Any other ideas?
