I worked with it when I was with Northrop Grumman about 2.5 yrs ago. They were running ArcGlobe, Nasa WorldWind or similar and they pushed it out to 20 dual core machines with what were modern graphics cards at the time and if I remember correctly the bottle neck was pci bus speed because of how much info was being pushed out through the network cards on the master.
I dont remember the exact stats, but they got pretty decent framerates with
arcglobe. Its not particularly hard to set up. But it was a bit of a pain to
tune unless you are already familiar most of the concepts. If you already have
nodes to test on, it might be worth a trial run to see if it might be
appropriate for your application.

How does Chromium stack up ? Its based on WireGl I believe and from what
I've heard isn't the fastest API out there - If your forwarding calls
every frame and rendering large databases in real-time wouldn't it be a
pretty heavy load on your system?....
