for very low speed connections
the VNC data transmission is superior over the X11 protocol.
there is a even VNC "driver" for X11, aside to the regular
VNC implementation which creates a second virtual display
on the unix server machine. (for windows, its just a screen grabber.)
to my knowledge, it does need lesser handshake in its communication.
despite this i found some VNC implementations transfering some Mega
of rubbish data until initialized. Maybe this is fixable.
