A couple of alternate viewpoints.  Dr. T. seems to have addressed your
direct questions pretty thoroughly, so I won't waste any time there...

As has been mentioned on this list, sharing views with a group of people
is often facilitated by having multiple viewers.  I did this with a
family gathering, using a Realist Red Button (Themelized), a Revere 22
(halogenized), and a Brumberger (halogenized).  Having multiple viewers
in use helps prevent that "waiting for my turn" syndrome.  The viewers
are loaded by you, and passed from hand to hand and then returned to you
for reloading.  With a few moments practice, one can get quite good at
this, and several people can be gazing at your slides simultaneously.
Of course the downside is the investment in viewers and having to lug
around multiple viewers, batteries, spare bulbs (just in case), etc.

Given Boris's recent cheerleading in favor of 2x2 slides, I will also
add that an alternative to a '50's stereo projector is a pair of modern
2x2 slide projectors.  I use a pair of fairly inexpensive Carousels, and
the inexpensive over-under stand (made by Da-lite) available from
Reel-3D.  Polarizers which I got from Edmund Sci. are simply taped to
the front of the lenses.  You can project Realist-size chips if you
mount in suitable Gepe 2x2 mounts, and if you use a twin SLR rig (or RBT
as I do) then you can project your slides as they come from the lab.  Of
course, this isn't precision mounting, nor are consumer-model Carousels
going to align the slides properly every time, but for my purposes (and
perhaps for yours) this is adequate.
