They did a demo of that software (I think that software, or a similiar emulation program) on the screen savers on TechTV a week or so ago. Said it runs like a pig, even on a 3Ghz machine and crashes constantly, but it does work. The version they had was version 0.1 so it's obviously just beta. Seemed like a neat idea and pretty impressive that it would work at all, but I don't use a mac so it doesn't really affect me.
