Yes, it probably was too glib an answer on my part. I think the initial
question peeved me (reminded me too much of being at a Microsoft TechEd
where they raved about the new feature of Windows that allowed you to
have multiple-head displays, and they were the first to implement it).
The problems you've pointed out, however, I think are Linux *and* XFree
(or probably just XFree) centric only; any X server that uses a frame
buffer that bypasses all that weird vt allocation stuff shouldn't suffer
the same problem (at least, that's how other Unix workstations did it,
which is my bad for forgetting that). The whole "one keyboard/mouse/screen"
concept reminds me too much of the design limitations of Windows.

Implementation issues. And do you need acceleration for anything else
but games and CAD (where you're likely to have a dedicated workstation
