Here is such a script. You would run

brlrun vmware blabla

and the braille device would then kept released while vmware is running.
When vmware exits, the brltty braille driver is resumed.

Dave, I'd say this could be shipped along BRLTTY.  This version will only
build & work on unices, not on dos/windows.

Ideally vmware would rather implement a virtual braille device, as is
done in kvm, and render it via brlapi.  That way the switch back & forth
VT or X window would be automatic. I don't know how such feature could
be pushed to them.
