Not sure, but if possible, the spots wouldn't rotate probally (I mean your object doesnt have to rotate 360, or krpano can't guess how many degrees you take per frame). It's more of a image sequence, like a movie.
Nice example indeed! Lot's of work to place all those hotspots!
What I ment with, the hotspots not rotating is, you can't place just one, and it will autorotate with the moviereel ;p But this is probally done at every frame right?
