Yes, extending WKT is the easiest solution. We just need to decide if this is 
the way to go.

The medium term goal is still to get ride of epsg-wkt completly, when 
epsg-ext-esri and his friends will be ready. I must admit that I don't know if 
epsg-hsql consume less memory however.

No, we don't use all the tables. We could probably do something simplier than 
the EPSG Access forms. But I agree that it is likely to be a boring task for 
many developpers. A non-developper with some artistic sense and GIS interest 
may 
be okay (if we know any).
