LensFun node for added lens distort options??

Hi

I posted an idea at blenderstorm a while ago:

Anyone care to comment on whether they think the idea would work or who might be already coding compositor nodes and have an insight into suitability.

A couple of additional links about lensfun:

And the authors site:

Thought it might be useful from an animation / batch image manipulation perspective as well.
