Totally cool! I used SpatiaLite (http://www.gaia-gis.it/spatialite/) LoadShapefile() function to import a shapefile into a SQLite db. The geometries are stored as BLOBs in a field named "geom" Then: sqlite> alter table ownership add column WKT_GEOMETRY; sqlite> update ownership set WKT_GEOMETRY=astext(geom); Getting MapServer to use the SQLite table was very easy. Recent versions of MS4W have SQLite support in GDAL. So simply adding CONNECTIONTYPE OGR CONNECTION "path/to/SQLite.db" gets MapServer drawing geometries from SQLite. I'm playing with a table containing about 15,000 polygons and performance is fine. Thanks Frank, for pointing me in the right direction.
