I started looking at this last August, but got stalled on the pgrouting demo not having a shooting star example.  I tried to get the FOSS4G 2007 examples running with no luck (some browser error with vector drawing).  Then I got distracted by other things.

But, maybe the pgrouting demo data could still work for this?  I don't fully understand the details of the various routing functions, but I don't really need an html file to load, just some SQL I can run.

The equator is so long, it could encircle the earth completely once.
