You guys were talking about using bittorrent sync to transfer episodes.

Bitlove.org offers a service that automatically creates .torrent files with webseeds for podcast rss feeds.

I use it on my site music.the-erm.com and it has a  js script that works with wordpress that will create button/link to download the .torrent file.  As I recall they had an API that could be used to create your own if not.

If you need a php script that has download resume capabilities with a bandwidth limiter I have one of those.  Just email me and let me know.  I'll send it to you.

Also I think bittorrent sync recently added versioning with 1.1.27 (but their faq isn't updated so I might be mistaken I seem to remember it in the release notes, but I can't seem to find them on the site.)
