I have successfully used averaged frames to make motion blur. A quick
(and dirty) way to increase rendering speed is to only render those
objects that move, using the +ua option, and then superimpose the
averaged result over the previously rendered rest of the scene. This
has the disadvantage of breaking shadows and reflection, but this can
be fixed, too, though it will make more time (render- and otherwise).
