VirtualPC ? (Score 1)

All of the sudden Microsoft's purchase of VirtualPC from Connectix makes a lot more sense. The core enabling features for getting Windows to work on a Mac are the same as getting legacy XBox games to work on a 360. Most notably you need a x86 emulator for PowerPC. VirtualPC is already the fastest most reliable x86 emulator for PowerPC which would make it the ideal starting place for XBox backwards compatibility. Having a know start platform and end platform could only make things easier for the developers.
