PhoneCaster.de is a nice service which offers podcasts via telephone. I received an email from them today which told me that someone had added my music podcast to their site (thanks anonymous stranger!).
This means that you can now listen to my podcast from your telephone or cell phone by dialing
(in Germany). I'm not sure if it works from outside of Germany, but you could try to call +49 931 663927 408. Please leave a comment and report whether it works or doesn't work.
There's quite a bunch of other podcasts available which you can listen to while in a train, on a bus, or while you're somewhere else without Internet access. This opens up some nice new possibilities...
