dual screen

Hi list

below an example off something i would like to achieve ....two identical
renders shown on two jit.windows. (finally the rendering will be done by
two different computers)
I would like to have the pivot-point of each render to be in the middle
of the two screens (it would look like one single render/window) ....I
cant find a way to change the pivot-point. (the lookat attribute seems
to get close but not close enough.)

...mostlikely an easy question for someone ...

thx Jurgen
