I hadn't chance to test yet but I think you're wrong concerning the host OS, you can run on Virtual PC 2007 runs on: Windows Vista™ Business; Windows Vista™ Enterprise; Windows Vista™ Ultimate; Windows Server 2003, Standard Edition; Windows Server 2003, Standard x64 Edition; Windows XP Professional; Windows XP Professional x64 Edition; or Windows XP Tablet PC Edition according to microsoft.
But you might be right for the hardware, I don't know if they use the same system as VMWare or not (if they do, then only my scanner will work)
This would be really nice though :)
