It makes not a whit of difference.  *All processes* within
a modern OS are virtual anyway; they can execute any
instruction.  (The illegal ones convert into kernel traps.)

The modern "virtual environment" extends this a bit; a
process can write into a display address area, and another
process picks up these writes (or just the data therein)
and displays it.  The first process doesn't have a clue as
to exactly where it's writing; it just thinks it's some
sort of display.  But even without such an environment,
a process can still write into a virtual address and the
framebuffer driver might pick it up for display.

Unused?  Hah.  XP isn't exactly efficient on that score. :-)

It already has; VmWare, QEMU, and Bochs come to mind.
Of course the desktop was highly virtual to begin with
anyway; an X window is an abstract token handled by the
X server, for example.

Linux.  An OS which actually, unlike certain other offerings, works.
