I chose to hack up ParaView. I did the following:

vtkSMRenderModuleProxy.cxx
     In Function void vtkSMRenderModuleProxy::CreateVTKObjects(int  
numObjects)
       Just before the closing brace of the function add the following:
       this->GetRenderer()->TwoSidedLightingOff();

This basically does what I want. I would actually rather add a toggle  
button into the UI, like in the 3D view properties pane. I am using  
PV 2.6 and on OS X 10.4.8 Intel (MacBook Pro). Could you give me a  
hint on where to look to add a button? Do I modify an XML file in the  
GUI or Server sectiosn?

I left my ParaView Book at work but if I can get started when I get  
to work after all the snow falls I can probably finish up.

Thanks for the help
