Doesn't provide channel changing though.

That does seem to be a stumbling point. If I put a DAB tuner with its own
amp in a central location, and then find a way to feed the output of the amp
to four or five different rooms (if such a way exists) then I would need
control over the tuner (up/down through preset channels) and the amp (volume
only) from each room. I don't know if that can be done.
