But what do we actually need PostGIS for on Cassini now that we have ptolemy? Just to give users PostGIS access?
From the Tool-Authors point we would need read-access to both, the osm-db mirror and the postgis db, no matter if they reside on cassini or ptolemy.
Despite that: having our own postgis on cassini would allow tool authors to play with different mapnik stylesheets and/or completely new rendering technologies. That's what the toolserver is for, right?
