[Paraview] multiple visualization pipeline at a time with co-processing

[Ufuk Utku Turuncoglu (BE)]

Thanks Andy. That is exactly what i am looking for. The broadcasting 
mechanism is not clear to me yet. Do i need to broadcast only the file 
names? Anyway, i will try to implement it and see what is going on there.

Thanks again,
Regards,
