Well, what I've come up with is to render the image
with pure specular-highlights, rest black. This is loaded
as an image-map, blurred via successive function/image-map,
and finally treated through another function which will
create white regions as white, and black as transparent.

I was planning on trying to achieve the same effect with
colored highlights, but haven't had the time so far. You
might want to have a look at it anyways.
You'll find it in my Downloads-Section, named Glare-Macros
(pretty far down). The URL is in my sig. There's also an
example animation to view.

Regards,
Tim
