Multi-resolution or tiled panos offer the possibility of so much more than just increased resolution which quite honestly from my view is most typically quite boring as a end to itself. Most giga pixel panos are a complete waste of bandwidth and viewer experience. There are very few worth looking at in detail.
But, tiled and multi faceted panos could provide a very interesting and changing viewer experience.
I would love to see multi resolution support dynamic alpha based on FOV and dynamic blend modes based on any consideration possible to program.
Just an idea to extend the artistic possibilities of this medium.
Cheers,
