As Burt has not been around the forums or on IRC for 10 weeks, I would not count on this particular plugin to be updated anytime soon. In fact, at this stage, I would assume it will not be updated at all. You can PM him and see if you get a response. If you do, please ask him to post here as well.
Remember, all the plugins on the WP plugin repository are GPL so anyone could take his work, update it, add to it, and rename it and call it a new plugin–with the appropriate credit given to Burt of course.
