Hi, haven't read the entire thread, but if you want remote visualization and HAVE GPUs, why don't you use VirtualGL? Then you would start it with "vglrun paraview", and ParaView would get a GPU buffer for direct rendering. It is very easy to setup, just google for VirtualGL, and if something does not work, email me...
