As long as we are throwing things in, I might as well point to the code
that GRASS is currently using:
Distance from point to point along a geodesic code from Paul
D. Thomas, 1970 "Spheroidal Geodesics, Reference Systems, and
Local Geometry" U.S. Naval Oceanographic Office, p. 162
Engineering Library 526.3 T36s
at least that one is easy to test :)
I am wondering if someone did set up a horse race between all these
various solutions, what would be the criteria to judge them on?
-computational time and difference from the "gold standard"?
