The comments package now works. You can create accounts, you can change your password, you can tell it to mail you your password (given a username) or your username (given your email address). You can log on and off. You can create comments and the comments are threaded.
Now all that's left to do is demonstrate integrating it into another application (the wiki is what I'm trying it out on), and polish off some CSS stylesheets for it (all the presentation is really in CSS - the XSLT just creates div tags).
