I have (and others too) been running Squeak on a remote host through VNC which
is a "remote-desktop-thingy" and I think that VNC sort of "solves" this particular
problem. vncserver is an X-server AND a VNC server at the same time - in short it translates the X
protocol to a much simpler "pixel-difference"-protocol which seems to suit Squeak just fine.

Anyway - just a sidenote that illustrates the problem!
