Exactly that, it's probably really worth trying, i not yet tried it with
isosurfaces, but i don't see a reason why it sould not work. For a
realistic horizon you will need quite a large water shape so you would
even have no choice.

That really sound quite long, the photon time is probably negligible
anyway with only 20000 photons.

I was just about to suggest a lower error_bound when i saw your picture
first, but it's probably out of question with such a slow render.
BTW, do you use some kind of manual bounding for the bricks?
