I had the same thought... how this effect could enhance porn picture sites. Given the dominance of "tube" porn sites, I doubt it will be as big as it could have been when picture sites dominated. However I could still see some niche sites using it to "get a better look" or on-page to attract clicks.
As I understand it, the depth map is created by slowly moving the camera while taking images of the same objects. It probably wouldn't work as well with a moving subject (even small movements).
