Performer already supports multiple channels quite nicely.

Performer 1.2 adds support for off-axis viewing frusta, which
are needed for proper stereo rendering. In 1.2, pfChannels
supports pfMakePerspFrust() which is like the GL window()
function. You could do this under 1.0/1.1 but it was tricky to
get the culling volume correct.

Beyond that stereo is entirely a matter of setting up the
viewing parameters. For the general case of an arbitrary eye
position w.r.t. the monitor, Michael Deering's SIGGRAPH paper
from 1992 is a good reference (except for its unfortunate use
of PHIGS notation).
