[sldev] University of Michigan Stereoscopic Viewer patch

[poppy]

This excites me, but I haven't got any hardware to try it on. Do any of you SLdevs have stereo 3D hardware? If so,

* whatcha got?
* what kind of triangle throughput / framerate do you get?
* how much does it cost?
* have you tried the patch on it yet?

+ poppy
