Urmmm my understanding was that Deluge had setup an ad-supported proxy server with a whitelist... it's got nada to do with TOR. You can use the browser in their torrent client to go to whitelisted torrent sites and download torrent files only.
You can Torify a few bittorrent clients already... there's just very little point. Tor is far too slow to support even the most patient of BT users.
Edit: Laughed when I saw your nick. Thought it said Bandido.
