When you say "representing", you mean you have a physical power wall that you are driving. Why is etherenet involved? Are you using a cluster of PCs? Knowing the actual set up is important here if you want useful advice. > I have got the moving around working but it appears that when glClear happens > it happens after each viewport is rendered, so there is a lot flickering.

Go look at the code in src/osgUtil/RenderingStage.cpp. The osg::Camera has a setClearMask() method which allows you to toggling on/off different parts of clear (which is done by RenderStage PRIOR to rendering the the Camera's scene graph). As to what is happening in your case I have no clue. It sounds like you have enough odd things happening due to your particular setup there is no way as third party we can guess at what is going on.
