I've been looking for various options where I can use an Android phone as the hub for a car/motorcycle/boatputer. Found the Real VNC Automotive product (or SDK I'm guessing) http://www.realvnc.com/services/mobile.html which seems to be directed at integrating your phone with a head unit.

Why not use a tablet in lieu of the head unit? Anybody aware of any products being developed with using the VNC approach (using an Android device for the dumb terminal)?
