Ok - I thought Postigs contained a superset of EPSG + other SRS defs.  
But its been  while since I was working on projection stuff so its  
not so fresh in my brain anymore.

This would be great. Ideally if we could come up with a way to  
automate updating the srs defs when we do a release - or build in a  
plugin to qgis to allow the users to update the srs database.
