There is no good way to do that as a half measure.  If you don't
calculate shadowing in general, you would get horrible flickering of the
entire scene any time *anything* gets between your avatar and the sun,
such as a lamp post or a tree.

The only other real solution would be to manually define areas that are
indoors vs outdoors, but doing that would actually be more problematic
than just doing shadowing to begin with.  So, we're back to actual
shadowing, which is exactly what Dave is playing around with.
