One possibility would be to make the 'background' town and render it with a
spherical camera (angle 180,90 IIRC). This can be saved and then mapped onto the
sky_sphere (or a smaller encompassing sphere) and used as the background for
scenes. I haven't tried it but it is a trick I've seen used by some POV people.
The latest version of MegaPOV also has HDR support so that the backgrounds can
shed light as well as contributing pixels. This would seriously reduce the
amount of calculation required for a scene since you can render the whole
background scene once and then reuse it in all subsequent renders.
See http://megapov.inetart.net/manual-1.2.1/patterns.html#hdr and
http://www.debevec.org/Probes/ for further information.
