Just ran across this and have tried out the trial version. This program seems to have some promise. The test pictures included seem to give a pretty good indication of the program's potential. The user interface could use some work, and it appears as if the refocus takes place in a smaller segment than the bounding box, leaving a border area that is still out of focus. I would probably consider this a beta version. It does have the potential to rescue some otherwise unuseable shots, and could be a hit if the bugs get worked out.
It is by Ronnie Kroonenberg, who also created the Picture Cooler denoiser program, which I like.
