This is a killer technology with great potential. An obvious "business" application is viewing rooms in a Bed & Breakfast, etc. My recommendation based on 35+ years of product development is that the current browsing UI is a little too non-intuitive and (in particular) disorienting for the average non-tech user who might be browsing looking for a B&B, etc. I'm by no means saying the UI is entirely off the mark or terrible. It's actually very impressive for a 1st offering. It's just that the non-tech user is going to find it far less usable (and therefore less likeable) than existing 360 pan capability currently in use by B&Bs (etc) from Apple(?)/Adobe(?). Picture yourself as a non-tech B&B owner deciding between Photosynth and the 360-pan technology. Also, there is great potential for tutorial use. Audio would be a great addition there. Alternately, sync'ing text to the current view.
