Very true.
It would be great to have a feature where we have access to a camera
object, with control of the:
1. camera root (where the camera)
2. camera target (where it's looking)
3. focal length control
4. and all associated 6D transforms.

This method of generating stereo images is correct, but also leads to
quite a bit of vertical parallax (the so-called "toe-in" projection) -
this is why many stereoscopic images are hard to view properly (usually,
edges of the image are out of focus). What you really want is a
non-symmetric camera frustrum (dunno how hard this is to do in pymol....)
where the two images should look along parallel vectors separated by some
distance (something like 1/20 the focal length). Check out Paul Bourke's
page for all the details:

Hope this helps.
