What makes me sad is that the original sgi engineers who developed glx were very careful to use x11 mechanisms for the gpu transport, so it was fairly trivial to send the gl stream over the network to render on your graphics card. "run on the supercomputer down the hall, render on your workstation". More recent driver development has not shown such care and this is usually no longer possible. I am not sure how useful it was in reality(usually if you had a nice graphics card you also had a nice cpu) but I had fun playing around with it. There was something fascinating about getting accelerated graphics on a program running in the machine room. I was able to get glquake running like this once.
