On a related note, one of the goals of GGI (at synergy.caltech.edu/~ggi)
is the ability to have a ggi-program (say ggi-povray to keep it simple)
migrate it's display to/from a local VGA mode, a local or remote X11
display, or even to a remote VGA mode screen. With a system call, it
would be possible to start sending the new screen info to "anyone" running
a ggi-aware kernel!
The security implications of this are..... awe-inspiring....
