No, not by a long shot.  I think that the only X applications
that ship with Apple's X11 server are the usual/original set:
xlogo, xterm, twm, etc.

Some third party stuff, such as OpenOffice for Mac is X11, for
example, but you can run that natively anyway.

I suspect that the interesting bits, like Quartz and QuickTime
will be dealing directly with Mach-level kernel details, like
the IOKit interface to the audio hardware, rather than through
Unix-level device driver interfaces.  So making them run would
involve replicating/emulating those parts of Darwin as well as
just the Unix syscall vector.  That's a significant chunk of
code, and significantly different from emulating Linux or
Solaris or other Unix-flavoured OSes.

Perhaps, but even if they use only Darwin interfaces, Darwin
isn't just Unix, so there would be a lot to emulate.
