You're wrong - mapnik depends on a local PostgreSQL database, not on the OSM 
API.

If you're going to do WMS, better to do it from vector data rather than from 
stitching and warping tiles together. You'll ensure better place naming and 
consistent widths.

WMS caches tend to not be efficient, so they end up not helping much. You want 
cached maps? Then use tiles.
