vtkRenderWindowInteractor supports one vtkRenderWindow per instance.
Don't even try this. :)

What you could try is attaching an observer to the InteractionEvent of
a vtkRenderWindowInteractor (IIRC), and then in the observer
explicitly synchronise another vtkRenderWindowInteractor by
transferring vtkCamera parameters for the Renderer in question.

Good luck,
