Something outside of the US and Canada would be great. The Jamaica
file works, the Trinidad and Tobago doesn't. Without address ranges a
traditional postal address geocoder needs that information to function.
In terms of collaborating with Paul Smith and the PostGIS geocoder
project, I think it makes perfect sense. After the response I made to
Steve Woodbridge's post this morning, I kicked myself for not
explicitly indicating that the group which is the natural one to
mutually provide helping hands to one another in developing a library
to create a Postgres stored procedure of postal address geocoding.
