Can't remember where I read it, but I saw an interesting idea about Amiga emulation. Not sure how much truth is in it, but it seems that running on a very stripped down Linux kernel they're going to try and make a complete emulation of an Amiga through a PC (I believe it required an x86). The idea was you could connect your amiga HD to the PC and a sort of emulation of the Amiga OS would be used. That way the only PC related thing would be your hardware and the BIOS which shows up. The rest would be left to emulation to gain maximum performance.
Again, I'm not sure how much of this is true and how much I've misread but it's an interesting idea.
