I'm probably one of the only people who actually own a Mac computer and doesn't own an iPod - but even I can listen to podcasts. And now OTN has started to produce podcasts about Oracle's technology - you can get them here: http://www.oracle.com/technology/syndication/techcasts/index.html
By the way for those not up-to-speed with the latest buzzwords podcasting is basically blogging in audio.
The first session is about EJB 3.0 - the eclipse plugin from Oracle and other things.
