Looking for remote desktop software that will work with openGL
 

I need to be able to open an openGL based piece of software remotely (like Maya or 3D Studio Max, for example). The server will be a linux machine (CentOS, currently, fwiw), but the client should be able to run on at least Linux and Windows. This will happen over the internet as opposed to over a LAN.

So far, I've tried
- "NoMachine NX" which is pretty good, but it seems to have some issues with GL. Maybe this can be fixed in xorg on the server (disabling overlays or something like that)? not sure.
- HP Remote Graphics Software (RGS) which works fairly well with Cent & Windows, though is sometimes a little slow. It also doesn't seem to be happy on Ubuntu, which is a pretty big bummer. It's also a bummer that it's somewhat expensive. That said, it's still the front-runner.
- VNC which was very slow.

Anyone tried anything else? It's imperative that it can transmit very complex rendered OpenGL properly. It's ok if it's slow to tumble/refresh, but it should be correct.

I also looked up that, but not yet trying. You can try VirtualGL

That looks very interesting. Will test it soon. Thanks for the suggestion!
