#What you say is true, but it also applies to human vision - when you shift
#your eyes to the side, the effective interocular is reduced, and therefore
#the degree of depth perception. The way around it is to mimic the human
#ability to turn the head, in order to look at things that are off to the
#side with the eyes still pointed straight forward from the face. The
#360-degree cameras would do this - I presume this is the type that runs
#the film past a narrow slit while the camera rotates. (The cameras should
#be rotated together as one body, ideally about a vertical axis at or somewhat
#behind the front nodal points of the two lenses, but using the rotating
#mechanism of one camera to drive both cameras may produce acceptable results
#if no subject is too close.) I'm somewhat concerned about trying to view the
#results in a viewer that requires the eyes to shift to the side - seeing full
#depth at an angle where depth would normally be reduced may or may not result
#in a reduced sense of reality.
#
#For viewing a 360-degree panoramic 3D photo in a manner that allows you to 
#rotate your head an keep the eyes pointed straight, there are several possible
#options. One is the commercial system called SPACESHOT (reference attached at
#the end of this post).

Did you see the 360 deg article in Stereo World a number of issues ago?
If you like I'll look it up and get you the volume/issue number...
