Ipod speakers with DAB?

Hello - I've managed to get my paws on a ipod, so now I'm looking at getting a speaker dock for it. In a perfect world I'd be looking to get one which charges the ipod, syncs it with the comp, and - most importantly - plays DAB. Does such a beast exist? If not, I'm willing to sacrifice the syncing. Can anyone recommend something?

Cheers in advance!
