The Odeo Blog: Podcast Amongst Yourselves: Odeo moves towards democratizing podcasting with DIY toolkit.

Once you create a recording, you can share it with your Odeo contacts or by email. Peeps are your Odeo contacts that you can add, delete, and otherwise manage. Or you can share your audio with the world by placing it in a channel.

This probably isn't revolutionary, but it should help people who need a little help doing stuff like this, for example professors that I help at work.
