you've got the basic idea right, i even helped "pricey" with a snippet on this last week, if he see's this he mght be able to post a link.
from what i remember; you position the camera in one place, use "set camera view" so that it renders what that camera sees to half the screen, then "sync" then reposition your camera, set camera view to the other half of the screen and sync again. this can be very slow though...
In the beginning, the universe was created...
This made alot of people very angry and it has been widely regarded as a bad idea...
