Because shared memory is just a graphics optimization and for most 
users, the difference between gtk-vnc and native SDL isn't noticable.  
So if a shared memory transport was the key missing piece, we'd have an 
awesome GUI based on gtk-vnc that just had slower graphics.

IMHO, the problem with an external GUI is that the interaction just gets 
too complicated.
