Nvidia fails with this.

Firstly, they used "active shutter technology" which has no advantages over passive glasses except that it costs far more, gives eyestrain and needs a power supply.
Secondly, they require you to have an Nvidia GPU. There is nothing preventing this being done on the CPU or an ATI GPU other than patents and lock-in via deals with the people who actually design the technology (Nvidia certainly didn't). Nvidia doesn't even have the best cards for the computation - ATI's have more than double the FLOPS.
Finally, their entire system is way too expensive and specialised to be propely used except in the ultra-high-end-PC market. Passive technology with a generic software implementation would be adopted far faster. But that wouldn't force you to use an Nvidia chip...
