I think someone should create a project at either Google code or Sourceforge and keep an up to date location DB. That way people will only have to download a zip/rar rather then enter in thousands of locations.

There should be at least one (but no more then 3) locations per administrative district. Example each Canadian Province and Territory should have it's capitol (including Ottawa) in there plus any other major cities like Vancouver, Calgary, Saskatoon, Brandon, Thunder Bay, Sudbury, Sault Ste Marie, London, Montreal, Moncton, Cape Breton, and Labrador City.

The zip/rar would most likely be unzipped from /usr/share/ so that we could hit both wdb-parsed.txt and the appropriate osso-cities.mo files.
