I just found out how to access my panos directly from my sdcard on my Android Desire Z.
Thought it might be of interest.
Heres how.
'First you copy your tour to a directory on your sdcard.
I just made a new folder named panos.
Then just copy your panos/tour to it.
In the browser write this:
file:///sdcard/panos/vtour/tour.html
Load and bookmark it and thats it.
I will make a special website gallery and copy it all.
And of course I use multitiles for it so that I can view superresolution panoramas offline
