I would suggest to use a shell script to render all scenes, script could
write some temporary file (based on current timestamp) and pass name of
such configuration file to POV-Ray using -Ddeclare=... command line option.

Seems like another good approach. Or, perhaps, it would be best to write a
small C program to generate POV-Ray syntax list of locations to some
location.inc? I suggest to use with programming language You find most
comfortable :)
