Has anyone taken a shot at Analytical Motion Blur?

This appears to be a very efficient method for motion blur that takes into account object movement and viewport movement.

Its actually nice to put in a Game
what really bothers me is that you
have to enter all those scripts into
the text editor in blender.

What’s wrong with blender’s text editor? Also, you can call shaders from external locations…

anyway: This particular script has an animated sphere and includes a basic raytracer. the actual motion blur part of the script is quite small.
