BitTorrent support for iTunes
BitTorrent is probably the most reasonable method out there for delivering podcasts. With as popular as some are, it would really help lighten the server load. I don’t think there are any immediate plans by Apple to add support to iTunes, so say hello to iTorrent.
iTorrent allows you to download BitTorrent podcasts from iTunes. It transforms BitTorrent podcasts so that you can update them just like any other podcast in iTunes. iTorrent also has the ability to smooth out the downloads for non-BitTorrent podcasts as well, so that you do not get frequent timeouts in iTunes when it updates multiple podcasts at once.
