You want to transmit the image or the image-blit-please protocol over
the monitor connection?  I think the monitor would need a few
improvements before it could do that well.

A nice thing about VNC-SHM would be the GUI could run on a different
machine to the emulator (SHM not used then), since it only needs VNC
and monitor, which can both be remote.
