Well, that is possible.  Is someone willing to do some leg work confirming
if that is the case, and documenting the correct formulation of the
coordinate systems described in http://trac.osgeo.org/gdal/ticket/2487
for PROJ.4?  Some sample test points would also be helpful.  Given that
I would be happy to update GDAL to support double stereographic and
update some other resources.
