I work with smaller utilities, primarily water/sewer and local multi-server operations. Many do not have internal GIS capabilities to update/maintain proprietary base mapping and rely on commerical maps or handouts from local governemnts. These utilities frequently run into to issue of what to do with new subdivisions or streets that are not on their basemaps. I have been suggesting that OSM might be an economical option for them to "fill in the gaps" at least until their main basemap service catches up. Not a perfect solution but a viable low-investment option. Hope to have someone take the plunge and implement soon.
