You are perfectly right. But I don't think that OpenGL should be used
for that. In this case we should take a closer look at M$'s avalon, a
scene graph description is much more what we would like to have here.
In this case we wouldn't have to transmit a lot data if e.g. only
positions change or something is highlighted.

Traversing this graph will be actually one of the features future
graphics hardware will have. So it's good if the Xserver knows about it.

I wanted to take a closer look, but I've been pretty busy lately.

Just my two cents
