Well, I'd say that you are right, regarding what real use of qemu will
be... That's better for users to be able to launch MacOSX on a PC, but
I'd like to also have a complete PPC box emulation to be able to launch
any OS, quite like qemu does for x86 target.
But, to have something to show, OK, it may be better to start up doing
the same as MOL does...
