Hey Marc I emailed Pandora support and got this respond...
Hi Ron,
Unfortunately, that device is not yet supported. Due to the interactive nature of Pandora, we do not stream audio using playlist files like many other online radio/shoutcast streams. As a result, it doesn't work without some additional development on the part of the hardware manufacturer.
The last part (about the hardware) sounds like BS to me, but wanted to know what you thought.
I don't think it's a case of the hardware itself being a problem. But unfortunately until we make an announcement about it, the best I (or our support staff) can do is reply with somewhat generic responses. Sorry!
An ex Pandora user here because of the lack of a functioning solution.
The site works for me unless I actually use it. Changing a station, song, or making a rating and the music stops playing. The only way to hear music again is by closing the web page and restarting.
I'm just glad I waited to renew my subscription until after i got the PlayBook...
