I previously riddled:

What do you get when you cross Podcasting with VoIP with unlimited cell phone plans with long commutes?

At the time, I knew some people working on CastCade (commemorative thong), which came and went without much of a whisper.

I mentioned a new wave of this technology recently, where you can listen to Guy Kawasaki‘s podcast by dialing (415)508-3265 from any phone.

There’s a name for this now, a VoiceCast. I have the number for Guy’s Voicecast, and found PhoneCaster.de, which has a ton of German VoiceCasts. Anyone know of any others? Especially something interesting, quick, and frequently updated?
