Are you saying that ST_GeogFromGeoJSON is the same as: ST_GeogFromWKB(ST_GeomFromGeoJSON(...)))? [assume the JSON is only polygons in EPSG 4326 format]

BTW, FME 2014 (in beta) is going to have a Mapnik renderer. This is great for performance, since one can first create the tiles, then render the clipped OSM data to each tile/zoom pulling data strait from the PostGRE/PostGIS DB.

Corporate firewalls keep us from Skype, but I can take email or pointers to blogs, etc.

We cannot sub-contract this work, so I cannot offer $, but if you know of a blog or article that outlines the process of designing the styles with mapnik for each level, and tips about dealing with dicing the larger zoom levels, that would be the best.

Delivery will be to leaflet, not openlayers, but yes. That is one path I am considering. I have seen some outlines of the Mapnik (postgresql/postgis) process at switch2osm.org/serving-tiles/manually-building-a-tile-server but that is for Linux, and we are a windows shop. I am also guessing that we should reserve a large block of developer time, since I have gut feeling that each zoom level has to have a filtered level of detail (from the OSM XML data).
