So, let's see if I can summarize the "issues."

1. If you allow the use of 3-D glasses, then you can accommodate viewing
the screen from multiple locations. But you still have to deal with the
problems of (a) making that same content viewable on different size
screens and (b) the focusing distance eye-to-screen being different from
the distance the eye convergence is trying to convey geometrically.

2. If you don't want to require viewing glasses, then you can only
accommodate a very small number of acceptable viewing positions. (Maybe
just one per screen, or perhaps column [as opposed to row] of seats in a
theater.) And you also have to deal with the issues in #1 -- screen size
incompatibilities and nausea.

3. An additional issue. Sailors who are unfortunate enough to suffer
from seasickness know that even if you can become accustomed to it after
days on rough seas, you also become unaccustomed to it after the sea
calms down. Next occasion of rough weather, same cycle all over again.
Possibly, then, if you don't watch 3-D content continuously, you may
suffer the nausea every time. And different people to different degrees.

Strangely enough, perhaps 3-D in cell phones is, after all, one of the
few media that will work well? Only one viewer per screen, small images
and/or short viewing times that may reduce the nausea-inducing effects,
and pretty much the same screen sizes for all venues, guaranteed.

I wonder why the hype concerning 3-D TV.
