For some time now I've been experimenting with podcasts together with Debi Jones and Rudy DeWaele. I've recorded and edited both podcasts from home so they were not very mobile, despite mobility as their main topic. For people who would like to produce mobile podcasts while on the go, Cellcast the "One Call to All" might be quite interesting (for the English version click on the little English flag on the upper right of their web page). All you need is a mobile phone, no special software required. A pocast is simply recorded by calling a fixed line phone number. Once done, the podcast is immediately available on the Cellcast portal, at your personal URL and via your personal RSS feed. The web site has a cool modern design with AJAX functionality, tags, tag clouds and is pure social media. In short: Web 2.0 at it's best!
