Mike,

Whew, that makes sense.

I"m afraid that would be hard to implement.

I do think that FWTools, PROJ, QGIS and VTBuilder can also use the same
projections support directory via PROJ_LIB, but if so it should include all
the support files.  Many applications (perhaps VTBuilder and QGIS?) ship
without the datum shift files, or may have older versions of lookup files
like "epsg".
