Digital projection and 3D

There's an interesting article on the New York Times site about digital projection and 3D. The thing that caught my eye about it was the screen refresh info. Apparently the 3D version of Chicken Little will be shown at "144 frames per second".
Now, I'm guessing they actually mean the projector will have a refresh rate of 144 Hz, and the movie itself will still have a standard 24 frames per second. But the point is that with digital projection, they can run the projector at a far higher refresh rate than film projectors have run, making it possible to alternate left and right images for 3D very quickly. With 144 Hz, each eye is essentially getting a 72 Hz refresh rate, which is what a lot of people run their CRT computer monitors at. That's pretty cool.
I wonder what the implications for this are for home theater. The article says they use a single projector. Hmmm...
