Not true. I've seen it ported to Windows, and I'm sure Cole would
welcome a port to Mac.

If you want to HELP the user, then tell them to use a management app
that has already dealt with the problems of consistent snapshots, rather
than making the user reinvent it themselves by clicking a gui button
that does incomplete work.

Yes, qemu has a gui.  But I maintain that it is mostly a mistake, and
that time spent improving the gui in this project, rather than porting
and improving better upper-layer guis, is probably wasted.  The Unix
philosophy is "do one thing and do it well" - we don't always live up to
it, but on THIS mailing list, the thing we do well is emulation, not
guis.  You are going to be hard-pressed to find reviewers, even if you
spend time solving the technical issues.
