Guest PC is an emulator of the x86 PC for the Mac OS X platform. We had a quick look at the product and we compared it to VirtualPC 6.1 that we also happened to have in-house.

The accelerator is not strictly a JIT module. JIT is effectively what QEmu usually does. The accelerator allows code to be copied directly from the executing program without going through translation. This can only work for x86 on x86 (I can't remember if x86-64 is supported yet) at the moment.
