I might be confused here, but if we're doing true binary
compatibility, won't the OSX native Quartz binaries work?  ;-)  There
would have to be an OSX compatible *video ABI* for that to work, but I
don't think Quartz would have to be rewritten.

This is assuming Quartz is in userspace or can be coaxed into Linux
userspace; I suppose it is possible it is a Mach process, I'm not that
up on the issue.

Of course, as you said, the true blue OSX libraries would be required.
