Focal blur is just part of the equation.

You need:

(1) A way to randomize the reflection. A `normal` statement with a very
small scale does nicely.

(2) A way to force POV-Ray to shoot a high number of rays per pixel
where the randomized reflection is. A small bit of focal blur (with high
quality settings) does nicely.

Together this gives you nice blurred reflections at a (hopefully)
reasonable speed.
