The solution could come from Adobe Air providing it still remains authorized. They already displayed single pano and a lot of new magazine made for ipad are showing virtual object. A sample (only a single VR but a more complex tour might come) : http://www.youtube.com/watch?v=zRWnZdp5ywg&feature=player_embedded
Concerning Quicktime VR, Apple dropped it many years ago although they mostly initiated the whole VT tour world in 1994. They still use Quicktime VR for computers objets only.
Now it would require a dedicated application, (adobe air based) to make virtual tour. It's up to Easypano team to check if it's worth it but it does make sense to look at it.
