The german radio station \"deutschlandfunk\" mentioned amaroK on their website as a podcast client right next to iTunes.

(sorry, german only)

I\'ve just downloaded some casts and copied them to my iPod. Worked like a charm!
The possibility to copy casts I\'ve subscibed automagically to my iPod on connect would be great.
