When like to have displacement instead of bump-mapping, you need to use
iso-surfaces.

Having real-micro-poly-displacement like having a normal{}, or a finish{} for
every object would be cool.

BTW.: The PixarRenderman uses real-micro-poly-displacement to generate
motion blur instead of multisampling of objects like MegaPov does. Its extreme
fast and the quality is *much* better. First and foremost, if you compare the
render times of these options, having the same quality.
