I have long thought of creating a C++ wrapper of Viper. It should be possible, 
with passing just NumPy arrays of coordinates, connectivities and data, from 
DOLFIN to Viper. But I have never got my but around to code it up. To put it 
clear, it is not one of my highest priorities...

Have you tried letting Viper read parallel vtk files, or would it still be a 
problem to call Viper using system? 

Does xterm work on Mac, and Linux, but not on Windos? Maybe you can "fix" it 
using xterm and then dissable parallel C++ plotting on Windows?
