Support for Drupal 6.x

Does you have any development versions of this module works with Drupal 6.x?
I work with Drupal 6 because I need a multilanguage site with subdomains, but 5.x can't do it.
I think that I ready to patch this module for my needs to work with Drupal 6, bit if you have some already work's versions, it's will be good!
