A thought, but I'm thinking simpler at the moment. A weighted normalized 
vector addition to the incoming normal in the direction of the point 
light(1).

(1) - Partly because in adding the ability to pass a vector to represent 
the point light, the same 'eventual keyword parsing' could be used to 
specify an arbitrary axis of rotation for other types of normal 
perturbation patterns I have banging around in my head.
