Actually, with a remote OpenGL display setup, OpenGL drivers can be active
on both machines. If Mesa supports the GLX protocol, and the machine he is
displaying onto also supports GLX, then the ldglite machine will simply
create the OpenGL commands and then send them over the network for the other
machine to interpret and display.
This is significantly faster than trying to render on the remote machine and
then send the bitmap graphics over the wire. However, it means that the
actual OpenGL rendering is done on his local workstation. The remote
machine simply creates the list of commands to call.
