Best approach to performer stereo?

Hi Folks -

I'm developing performer stereo visualization on a multipipe Onyx2.
My implementation is basically a customized version of perfly with
some old example code from stereo.c (~10/97?) folded in. This uses
quad-buffered stereo with a dual channel group (left/right eye),
which I've customized to handle the multipipe configuration. While
navigating works fine, I'm having difficulty with changing viewpoints
or path playback since I have to manage left and right eye channels
separately, even though I've initialized and attached the channels
like this:

for (i=0; i<NumChans; i++)
{
       ViewState->chan[i] = new pfChannel(pfGetPipe(i));

       ViewState->rightEye[i] = new pfChannel(pfGetPipe(i));
       Viewstate->chan[i]->attach(ViewState->rightEye[i]);
}
...

/* Attach channels to master channel to form a channel group. */
for (i=0; i<NumChans; i++)
     if (ViewState->chan[i] != ViewState->masterChan)
          ViewState->masterChan->attach(ViewState->chan[i]);
..

Discussing this recently, it was suggested that this might not be the
best approach and/or that I'm using "old-style" stereo. Could anyone
comment on whether this is true and what is "new-style" stereo? Any
code examples using new-stereo (or any stereo) would be greatly
appreciated!

TIA,

- Steve
