This is not exactly correct.  Most of the X telegrams are not "pixel"
based.  The pixmap messages are for transferring icons and for graphical
applications.  So if your students are using image intensive or graphical
applications, like tuxtype or tuxmath, it will have to transfer lots of
pixel based telegrams to the clients.
