Yes, or you could simple chan share the position, they need to share the
same scene and sharing stuff like LOD & earth sky (with fog) can also
help. There are a few other tricks which are less well known like making
sure that localviewer lighting is enabled in the light model to minimize
lighting discontinuities across channels.

You can get 2 channels from a basic system or if you go for the channel
option you can get 8 channels. You always have the video bandwidth to
drive 3++at++1280x1024_60Hz but obviously you'd need the 8 output DG for the
3 channels.
Ensuring the right graphics channel is output to the right video channel
is simply a matter of opening viewports in the right areas of the
framebuffer to match the channel layout you create using the ircombine
program.
Cheers,Angus.
