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.

There is a solution to the problems of the demise of CRT > displays.

The advantage of this > approach is that it allows for viewing by groups of people > without the expense of shutter spectacles.
