There is no layer of OS emulation if you use an x86 emulator. An example
of an x86 emulator is QEMU. You run "qemu wine <windows program>" and
that is it.
You seem to be thinking that an x86 system emulator (e.g. VMware,
VirtualPC, Bochs, etc.) is required. They aren't.

No, it doesn't.

Which is exactly what QEMU does. QEMU already works on PowerPC hardware.
<URL: http://fabrice.bellard.free.fr/qemu/>. All that is needed is for
someone with access to port it to Mac OS X.
That someone could be you, and you'd have achieved what you want.
