DAB is the european standard for digital radio. It broadcasts MPEG2 streams at up to 320kbit - it's been broadcasting for a couple of years now, though the tuners are still pretty expensive - about $1500 for a cd/dab tuner combo I think.

We're using a DAB module, which means we have limited access to the digital datastream (we get all the audio, but we can't get full-rate digital downloads).
