sorry for my unprecise answer.

I had euclidean distances in my mind and usually
you have simple geographic lat/long in a shapefile.
Thus you can use PROJ4 to convert lat/long coordinates
and then perform a simple euclidean computation of distances
e.g. to express meters within a small area.

I am not aware of distance calculation routines in PROJ4
(haven't sought for it either :-)

OpenMap graphically displays distances on different projections
moving the mouse around - quite nice.

Cheers
