I really like the concept beind this program. My first thought is that this would be really usefull for schools. Reason is that some parents refuse permission for the school to publish images of their kids. I have seen it result in some children being excluded from group photos, school camp photos and so on. With this, those kids need not be excluded, it would be simple for the school to edit out their image without having to move them out of the photo altogether.

Nice Hunt.
