So you actually mean that you should apply a general compression   
without any consideration of the image subject . That would mean you  
have to set it very low and the download sizes  will be huge for a  
2000x2000 cubefaces.

I done some tests and you will have 6-7 mb per fullscreen panorama   
at a 60% (Mac) compression.
