Two non-import thoughts:

  In Mass we have a tiled raster datalayer rendered from the vector
  parcels database.  This is transparent with white lines for lot lines
  and address/parcel.  It's highly useful for figuring out addresses and
  also adjusting geometry of open space, parks, etc. when making landuse
  polygons.  Code (by Jason Remillard, not me) is at:

  Even though the current mostly consensus is that property lines don't
  belong in OSM, they are really useful in making maps.  So if you can
  produce and host an osm-format file with property lines (I use
  boundary=parcel as the tag in my private files), then people can merge
  them with the OSM data to produce e.g. a garmin-format map or a map
  for OSMand, or their own mapnik render.   Perhaps OSMF-US has
  resources to host these files.
