You don't need xglobe to generate the coords.  In fact it doesn't help at
all for making them.

xglobe is similar to another pgoram (xworld?).  I prefer the maps that xglobe
produces (pictures of a sphere, texture-mapped with an Earth-map presumably
constructed from satelite photos).  The .xglobe markers file is compatible with
that of the other program.

You can also just add a rho = 4000miles (or about 6400km?) and treat the coords as
spherical coordinates, then convert to X/Y/Z and find out who's nearby.  (Though
for many, "nearby" probably is small enough that you could probably get away with
treating the coords as X/Y coords in a plane (unless you are very near a pole.)
