Check this one out:
//www.luminous-landscape.com/reviews/software/optics-pro.shtml
I haven't actually tried it as I do not have one of the lenses listed, but if it is as good as it looks it is quite something.
You need to mouse hover over some of the images to see the result.
If I had the right camera/lens combination I'd be interested.
Anyone actually used this? It looks great on that review site, but it is always better to find someone here with first hand experience.
By the way, for anyone who hasn't come across it, Luminous Landscape is an excellent site for info, reviews etc.

I have heard that zoom lenses are more likely to have distortion aberrations than other types of lenses (except superwide and fisheye).
It occurred to me that a simple linear resolution chart could be used to measure the amount of distortion at various settings of the zoom lens.
One could then determine whether or not the Pro-Optic or similar software would be useful for a given camera. There is other software available as freeware that can correct cromatic aberrations, in particular, XNVIEW, made by a company in France.
At first glance, it appears to me that the Pro Optic software may be introducing distortions in an attempt to correct for normal optical perspective.
For example, it is normal for the lines of a building to 'lean' due to the cameras perspective and not because the lens distorts the image (though curvature is an artifact of the lens). In at least one example
on their website, a correction was made to an image that corrected the lines of a building making the building appear somewhat askew from bottom to top. The perspective was wrong.
But it also appeared that the software does much more than correct distortion, it also seems to correct astigmatism and spherical aberrations. Probably something to be used, like all software aids, judiciously and sparingly!
