Since the issue has been raised again, I'd just like to inquire about
whether or not the direction was settled regarding with window system
-- is X11-based graphics in some form going to continue to be
supported (many of our primary concerns)? A fast MATLAB desktop
running natively in Aqua on Leopard may convince me yet to switch to
actually using the desktop (which I do not currently at all).

However there should be a way to maintain the basic X11 forwarding/
plotting functionality (and run MATLAB remotely via terminal) and
still have a nice GUI for those who are working at their primary
machine. Probably some or many of us do both, and I certainly do not
want to use slow, difficult-to-secure VNC for my remote MATLAB usage.
I'd much prefer having the lightweight command line availability, as
it represents my core MATLAB usage. I suspect that latter sentiment is
not the majority, though I would be happy to be surprised.
