Have you guys considered offering a download of the video version of the podcast? I use a podcast manager to download various video podcasts overnight and watch them later on my phone and tablet. If bandwidth is an issue, maybe you could offer up a RSS of torrents of the podcast and only seed the most recent couple shows? I'd gladly seed the torrents for as long as possible. I can download them off of YouTube if I need to, but it is a very manual process for me right now.
