[vtkusers] parallel rendering from Python

[Berk Geveci]

It sounds like that example is out of date. Look at
VTK/Parallel/Testing/Cxx/TestPStream.cxx for a C++ example. It should
be relatively easy to translate to python. If you feel like fixing the
example, I would be grateful if you contributed it back.
By the way, it may be easier to use ParaView's python interface if you
want to do distributed processing.
