As I mentioned in the podcast here are the resources below if you want to check out podcast hosting I recommend the two below.
 
Podcast Hosting
Blubrry - If you've had the opportunity to go to any of the podcasting conferences you've probably seen their booth. A great company that I'm helping with some enterprise clients. Great hosting that encourages you to own your RSS feed and gives you a free Wordpress site along with IAB certified stats, vital if you're working with sponsors.
Podbean - Another great hosting service that Patrice host her podcast on so it's always a top contender for affordability and dependable service.
