Mr Sid, first I'm not american
second: I tried the holographic stuff (I think german ELSA guys have the best solution). I actually bugged hitech into implementing the Z buffer thing a while ago. Outcome: forget it. Multiple problems: drivers are shaky, also screen looses a lot of brigthness when you look through those glasses. Since refresh rates are so high, most applications generate flickering (suspicion: heavy IRQ load, funny DirectX stuff gets the stuff out of sync from time to time). As well, the Z buffer thing on graphic cards seems to cheat, some stuff will appear being 'out-of-plane' and that's VERY disturbing for your 3-D perception. Lastly, you loose about 20% of the side-view (for the holographic overlap) so you get a tad of a 'tunnel'-vision. There were 2-3 games that looked good though (best was Laura's demo ;-)
This stuff has still some way to go. I'm waiting now for DirectX with multiple cards support and will bug hitech into implementing support for it. Imagine having 3 paralell displays, one with 6 view, one with forward and one with the pin-up-of-the-day. Oops ;-)
