"Hmmm" indeed! It really might depend on how Apple's ATSUI renderer 
deals with OpenType -- if it ends up using the same interface in XeTeX 
as the ICU renderer, then for the internal purposes of fontspec at 
least it's the font technology that counts and not the renderer. (Which 
is where I'm having the issues.)

I think I might let this one sit until I've got a firmer idea of what's 
going to happen with Tiger. (Do you actually not know anything about 
Tiger's OpenType support, Jonathan? Or are you just good at sticking to 
NDAs? Oh wait, you can't answer that without implying that you are 
indeed under one, so it's probably better to ignore the question.)

Anyway, even if Tiger does support Unicode, I presume that you're going 
to be wanting to stick with the ICU renderer as much as possible in 
order to be able to keep XeTeX as platform agnostic as you can...
