Podcast distribution idea

You should check out bittorrent sync www.bittorrent.com/sync .

You get to distribute the podcasts, just generate a read-only secret and distribute that, when you add new stuff the whole folder is synced with a bittorrent backend.

You get to distribute the podcast, and it costs you nothing in terms of bandwidth. You'll only have to get people to try it, and it's an automated alternative to just dumping the podcasts to a torrent tracker.
