I'm afraid you can't use OpenGL directly and pretend that it
your app still works in clustering. OpenSG needs to trace changes you
make on the scenegraph in order to transmit it over the network,
so you need to use the OpenSG primitives to do that. So... you
need to say goodbye to OpenGL! But I'm sure the core developers
can explain more in detail this issue....

Out of curiosity: Why do you want to switch from OpenSceneGraph?
