Lightroom - programmatically calculate image sharpness

It would be nice if Lightroom could calculate image sharpness (as in, camerashake) programmatically.

This would help my workflow because there are frequently cases where I took several copies of a shot at slow shutter speed, and want to see which is the sharp one, without having to manually compare them. (I would also like a quick way of spotting 'blurred' shots right away in general.)

It could be a number ('on a scale of 1 to 100, how sharp is the sharpest bit of the picture'), which you could set to appear as a badge on the image thumbnail, or else a visual display such as a colour-map of which areas are sharp (green = really sharp, red = soft, or something like that). The latter could also indicate what's in focus. Should be available from the main library screen so you don't have to look at the photo to see how sharp it is.

Somewhere in this feedback system is my similar feature request: analyze the frequency (FFT) of a subsampled area (eye, teeth, etc) across several similar images. Automate the subsample matchup with a simple least-means-square match. I like Rob's idea, too. Maybe a heatmap overlay? Red for highest frequency, blue for blurry areas. Overlay it at a user-set opacity. hmm..

Rob: Agree it's very similar (wow that search really doesn't work). I think it would be nice to have some summary information in the library view too, though.
