 On Linux at least, dual-headed nVidia Quadro cards support a special
 stereo clone mode for precisely this situation.  It is 100% compatible
 with existing stereo 3D software using the OpenGL quadbuffer API, and so
 one digital projector simply gets the left image while the other gets
 the right.  Both projectors display the non-stereo content, so the
 effect is exactly like using shutter glasses on a CRT with
 stereo-3D-in-a-window.
 I don't know if that same capability is available yet on Windows or Mac,
 but it is a great solution for building inexpensive "geowalls" with
 full
 stereo 3D software compatiblity.
 Cheers,
 Warren
