Hi Sam!
Yes, this is what I was asking for. I've managed to make a similliar effect
with the Gimp. Upper two are the original images rendered with MegaPov,
lower left is the final image with faked DOF, and lower right is depth-map
corrected by making difference with gray, to shift focal point to the
middle.
My only question to you is about applying blur: Is there any way to apply an
effect selectively relative to gray map? In my image I've made layer mask
and then converted it to selection - Is it the right way?

Still I am investigating possibility of making this effect directly in
MegaPov in a similar way like "convolution_matrix" macro works, but with
creating new matrix for each point. It will be probably very slow, but
maybe faster then original DOF procedure.

Greetings!
