I was wondering that as well. It wouldn't be too hard to pull individual frames out of synced movies, script panotools to assemble stitched frames into spherical or other panoramas, and then reassemble into movies. I've seen commercial firms offering similar services. I also know that about 10 years ago there was an unfortunate bit of a patent minefield surrounding panorama software, I'm not sure of the current status of those patents or techniques like these.
