Come on, Microsoft! This would be such an easy thing to add to the Photosynth app. It would take one programmer maybe a week or two, if even that. And it would absolutely blow people away and make headlines and buzz. And it would allow panoramas to finally take their place alongside photography, video, and literature as a true genre of human expression. Imagine standing with your phone or tablet in front of you, and moving it above you and around you without touching the screen, in order to look around a museum or a mountaintop or an ancient ruin as if you were really there.
Is Microsoft just giving up on Photosynth and leaving it to die? Is that the plan? If so, then I guess just forget I said anything. But if not, and if somebody, somewhere in your company still cares at all about this project (not to mention caring about changing the world a little bit) then I can't understand why you would not want to add this feature!
