No, not really.
I'm sorry if the title is not worded the most clearly, but what I am asking for is the ability to make photosynths out of multiple spherical panoramas rather than multiple ordinary digital photos.
What Google is currently offering is the ability to present multiple spherical panoramas in a slideshow with no spatial transition between them and no automated image matching which would provide the information necessary to spatially transition between them.
What I am asking for is nothing short of being able to upload multiple spherical panoramas taken throughout a space (a living room, my own street, a public park, a garden, a cathedral, etc.) and have Photosynth automatically align them spatially, recover the geometry seen in multiple panoramas, and provide spatial transitions between these panoramas (ideally while projecting the panoramas onto the recovered geometry).
In short I want nothing short of the ability to shoot our own Streetside.
