Danny Maas at tilttv.blogspot.com - Teachers Improving Learning with Technology - deserves a lot of respect. Visit his site and experiment with his pod and videocasting experiences. You'll come away refreshed, amazed and just a tad envious. But don't worry, Danny is a fellow Nettraveller who will gladly help you become an avid netcaster too!
When I find half his energy, (and some time), I too will post a vodcast!
