I take a fair number of casual action shots – mostly of the kids. To get something to come out I often take a handful of pictures in a row; even that's often not enough, or the "right" scene happens in between these slowish frames. This could be cool for those cases.

Except... I also get annoyed sorting through those pictures afterwards. It would be interesting if with some post-processing it could sort through the pictures some for me, identifying distinct pictures, or filtering out ones that are clearly bad (mostly too blurry), or if fancier maybe doing eye or smile detection. I want to capture the moment a person looks up, before they think about the camera.

Another cool case would be taking photos of movement. If I can track the movement with the camera the picture can come out surprisingly well. But tracking movement is hard. If I had several seconds of pictures, over the course of that time probably I'd track the movement well enough for a few of the photos to come out.

If I remember correctly the automatically sorting through your pictures and picking the best is exactly what Google announced for Google+ at their last I/O keynote.

That's a cool feature, and not easy to implement. It generally ends up being a machine vision problem. (Google has both great talent and a lot more resource than a single-founder self-funded engineer like me.)
