IIRC the wording in the EULA is "on Apple branded hardware". My argument is 
that my laptop has a 'kin big Apple logo on it which doesn't magically 
disappear if there's a layer of software between the hardware and OS. The CPU 
and RAM is still physically inside a box with a 'kin big Apple logo on it - so 
it's hard to argue that the OS is no longer running on "Apple branded" hardware.

Later versions of the EULA allow for virtualisation - so making the discussion 
moot for newer versions of the OS.

Sort of - it's unique enough to make spares expensive :-(

That's a rather sweeping statement - it's what I've been using as my main 
environment for a looooong time. Ooh what fun it was finding out what did and 
didn't work in 10.0 :-) It "mostly works", there's plenty of native software 
available for it, with the likes of Fink and Ports I can run loads of *nix 
software, with WINE (or Crossover) I can run Windows stuff, and with Parallels 
(or  VirtualBox) I can easily fire up virtual machines for other stuff.

Xen doesn't "support" or "not support" any specific OSs. Not even Linux to be 
pedantic - there's Xen support in Linux, not Linux support in Xen. In any case, 
I could see there being some issues in "officially" supporting OS X as a guest.
To "support" OS X in the manner I think you mean would mean emulating some 
Apple proprietary details - that would almost certainly mean someone signing a 
non-disclosure (even if Apple were prepared to co-operate) and that would be 
orthogonally incompatible with a FOSS (especially GPL) project. Even leaving 
that aside - who would pay for the lawyers that would almost certainly be 
needed.

But as mentioned previously, I strongly suspect that if you can get a 
Hackintosh working, then Xen could run it with the right settings.

If you mean about unique hardware is that Apple use special Hardware then you 
wrong. They reverse engineering PC motherboards and make their own motherboards 
and thus their hardware slots and...must different from PC but I mean is that 
Apple use Nvidia or Intel or AMD for VGA, Kingston or corsiar or.. For RAM 
and... and all of them are PC :)
