E.g., how many points can be displayed without flicker? The big problem I see with both the Spacegraph and TI's system is that they both produce "cloud" type images. Transparency is useful for some applications but usually it gets in the way of understanding complex structures. It's not at all well suited for CAD/CAM or architectural modeling in which solid surfaces and lighting cues are important. But it might be useful for missle trajectories or air traffic control. For most things, I'd rather have head mounted stereo displays. Where will the big demand for these devices come from?
