Even, Hermann might be right. From reading several sources: http://gge.unb.ca/Pubs/TR46.pdf http://www.manifold.net/doc/double_stereographic.htm it seems that double stereographic is oblique stereographic as long as the origin is non-equatorial or non-polar. The actual denomination "Double Stereographic" seems to be a ESRI by-product that refers to "Oblique Stereographic". However, ESRI's own descriptions of these projections are, at best, vague.
