Well, I thought about this for a while and this is what I've come up with - it's iterative and eats quite a lot of shader instructions, though. Also, it gets distorted by aspect ratio.

I've put full comments into the comp shader that should walk you through the steps. Also see Cope's excellent Pixel shader guide for more info on shaders.
