I just got this module into Drupal.org.

See http://drupal.org/project/uc_addresses.

I also added a page on this site: http://www.ubercart.org/contrib/4872.

The code in CVS is pretty much the same as the last archive posted here except that I added a lot of check_plain() calls for security and tweaked a few things to match the Drupal requirements.

Please add bugs to the official bug report list for the project.
