Indeed you don't just need openGL for rendering on the client, you also need a GLX layer (openGL over X) --without-- the DRI hack (direct access to local hardware, which in the case of a ltsp server is not very well suited). Unfortunatly AFAIK there are not so many card that have true GLX. By the way, if your thin client is a bi-xeon or such, you can enable GLX in the lts.conf file, GLX rendering will be done by the cpu, not very useful for production environnement, but a first start for running glxgears and such.
It was mentioned earlier that 3D rendering should be less bandwidth hungry than standard 2D. I remember to have reached 8MByte (yeah, that is not a bit) of traffic with a google earth exported though GLX. It was quite reactive though. I didn't had time to tweak it, so perhaps it can be greatly reduced. However, it looks like gigabyte switches gonna be mandatory in the future !
