Doing HDTV projection from ONYX, (especially in Stereo)

I am trying to discover, FOR CERTAIN, whether the ONYX system is
capable of doing HDTV video in stereographics mode. (Preferably at 120HZ or
so, not 30Hz.)
The Onyx documentation I have read seems to suggest that it is NOT
possible. It also (ref. setmon files) suggests that the highest HDTV
resolution can only be done at 30 Hz interlaced.
Almost everyone I have spoken with things it is not possible to do
HDTV in stereo, and that the best I should expect would be 1600x1200 (4:3 /
"NTSC" format), and would require two pipes, connected through SWAP Ready
connector, probably with genlock(??).... If this is true, does that mean
that we would require TWO projectors (one for each pipe / eye)?? Or is it
possible to combine two pipe output into a single projector input?? (maybe
through a combiner box of some sort?)
What makes it more difficult to determine the truth of the ONYX
capabilities is the fact that I "have heard from someone who knows someone"
who claims that not only is it possible to do HDTV in Stereo from an ONYX,
but that it ALSO can be done at a 120Hz refresh !! AND, this someone has
seen it done !!
I would greatly appreciate hearing by email as soon as possible ANY
info that may be helpful in discovering the truth. Whatever equipment,
additional processors, pipes, RMs, REs, whatever, is necessary does not
matter as much as knowing What is possible and HOW to make it work.
Thanks in advance, jbu
