I can't think that it would be of great interest in still photography because the photographer wishes to control the filter effect. It could have some utility in high-end panoramic photography though, particularly with the automatic panning devices such as:http://www.roundshot.ch/xml_1/internet/de/...cation/f469.cfm
Presumably this would be a very expensive "accesory" so it would only be pertinent to high-end, probably professional applications.
Good luck to your friend. Let us know what happens.
