I remember reading somewhere that there was a camera mount mod that
went under the nose of the Diamond DA-40, but I can't find it anywhere
-- not even Google. Anyone know what I am talking about?

On a single-engine plane, I suspect that the prop would interfere too much
with such a camera, if one goes to the length of mounting it outside.

On the other hand, a twin could work much better, and Diamond have done
some work in this area already:
