I would think this is possible in hypothetical terms, that is, if you know both
pipes are started at the exact same time, and consistenly and continuosly
render the scene at the exact same rate I guess it could be done, but I would
think you need to add some kind of sync between the two pipes. Why don't just
use quad-buffers (assuming the Sirius can work at 120Hz, and you wanna do 60Hz
which I don't really know)
