There will be, undoubtedly.  Brad Grantham had X11R6 running for
a time on his machine.  Maybe he still does... :)

Not at all.  But you can mount an A/UX filesystem read-only
just fine.  But you won't be able to build X11 under A/UX
and expect it to run under MacBSD by copying it over.  You'll
get a warning, something like, "Incompatible binary format."
(or maybe it's "Unrecognized"?)
