The n computing stuff really is quite nice. I use concurrent RDP sessions from PC based clients all the time (also from my android phone, which is REALLY nice), and really like the things that allows you to do. That's basically all the n computing systems are as well - RDP thin clients. as such, they are every bit as fast as the console session, minus some hardware acceleration features. They would work quite well in a car environment, but would have to support the touchscreen, and of course, OM would have to be able to work across instances, and even across sessions.
