Hi Steve, Yes, you can process the result of core Driving Distance function with Convex Hull function of PostGIS or with point_as_polygon function of pgRouting, but there is a wrapper around this core function already which returns you a polygon (http://pgrouting.postlbs.org/browser/trunk/extra/driving_distance/sql/routing_dd_wrappers.sql#L78) right away.
