This is exceptional! I wonder it a similar concept could be done for skin (but in reverse - so the more "imperfect", the higher the red content). I need to check out these new P6 nodes you are using. You are right....these things can't be blurred - one pixel on the render can't get material room info on another pixel (not through nodes anyway). But some ideas....in this case you've got obtuse (is that the right term) angles that you are trying to effect the color of. /If/ they were accute, you could use an AO node to determine if other polys were in the vacinity (use it in conjuction with the diffuse node). Also, have you tried using the gather node. It has a parameter to gather from a specified angle - if you plug in 360degrees it might be a way for you to detect what the nearby polys are doing.
