I've been working on modifying POV-Ray to do this.  The (rather buggy)
source code for my first effort is available at
http://www.geocities.com/rengaw03/download/skypov.zip if anyone is willing
to spend the time trying to compile it.  Since something has added a bunch
of extra newlines to various files, I expect it will take about an hour to
get the source code to where it can be compiled.

I'll try to get a bug-free compiled version ready tomorrow, but I can't
guarentee anything.
