XM is not available in the UK as it is a satellite service here in the states.   They do offer online programming by subscription - www.xmradio.com, but I am not sure if they are able to sell the service outside of the U.S.

I have XM but I did not have a chance to listen yet. Some early reports from those that heard it is that Dylan is very articulate and knowledgable, and the playlist is eclectic as Big Tim mentioned above. The initial response is that this show is better than expected. I wonder how long Dylan will keep doing it.
