Bruce,
Can you provide some supporting detail on why these alternate projection names are valid? Are they "autodesk wkt"? If so, perhaps we need a morphFromADSK() and morphToADSK() methods as we do for ESRI. Alternatively we could have OGRSpatialReference::Fixup() method try to cleanup these non-standard names and set them to the standard values.
What I don't want to do is have all parts of the code have to understand many variations on the projection names.
I'm setting this as a 1.4.2 milestone since I don't think we can address it for 1.4.1. If the changes are quite broad we may need to limit the changes to 1.5.0.
