3D Scanner for iPad by Structure Sensor. New Way to do Photography?

I was wasting some time on Facebook today when I came across a friend's post to a link. It was a video of someone testing out the Structure Sensor 3D image scanner at Ripley's Believe It or Not museum.  Amazing stuff, and I think the real estate applications for this would be awesome.  You could take 3d models for an out of town buyer where they can see rooms almost as if they were walking through the house themselves! It's expected to be out in April of next year, but the first batch of preorders in sold out. I'm tempted to go ahead and preorder one for May delivery. *Excited*
