My favorite home audio receiver Sonos is reportedly about to release version 2.2 with Pandora support.  I'm looking forward to this in a big way.  Now if only XM  would do a deal with Sonos, I would be a very, very happy camper.  Until then, I continue my Media Center->Xbox->Sonos workaround for listening to Flight 26 from my home theater.

Update: Version 2.2 has now been released.  Unfortunately with it comes the cryptic news:  Pandora (a free, ad-supported service on PC) comes with a subscription requirement after 30 days for Sonos.  This is a little disappointing as the only value you seem to get for your $36/year.  That's not much, but the only value offered is 100% free of advertising?  How about being able to play a specific song when I create a station based on it?  I'll probably still drop my Rhapsody subscription in favor of this cheaper alternative.  Sonos- if you want to talk to XM, give me a call ;)
