I'd kill for a pandora and hvac integration on centrafuse that they have there.
Although the HVAC plugin was strictly a graphics demo, the underlying logic could be adapted to a functional plugin pretty quickly.
I think it's pretty likely that Pandora will eventually be released. They have a fairly stringent licensing program and a significant backlog of devices waiting for certification, so it's a little hard to say when.
In real-world daily use (but on Pandora's beta rather than production servers), the Pandora plugin is very stable. As is true of any streaming media source, how pleasent the user experience is will in large part be determined by the speed and reliability of the available in-car internet connection. Clear 4g here in Vegas is generally very good. Initial station loading on teatherd 3g is a bit slower, but playback is essentially identical.
For those unaware, Microsoft Auto is a set of VR, TTS and other technologies and frameworks riding on top of a base OS, in this case WinCE. The Kongatec prototype reference boards were a little rough in spots which made getting everything to work correctly a real challenge. Some long nights, but a lot of fun.
