In research and design applications it's often one or two people at a work station. Simple double image red/green 3D or even vertical lenticular is possible. Sun had a system I saw demoed in the 90s for looking at and rotating molecule simulations in 3D.

I did some large (1.5m high) lenticulars a few years ago for a cruise ship that contained 8 separate static images. As the passengers walked past the image changed. No glasses needed. Lenticulars have a quite wide viewing angle, and I would guess that putting up two images (the stereo pair) on a lenticular screen is possible. Digital images are stable horizontally - but the vertical lenticular lens sheet would have to be almost directly on the surface of the screen image.
