non-CMS based Open ID?

[Chris Chiasson]

Assume someone has his or her own GNU/Linux server containing a
website where pages are built from XML source using a makefile. This
person does not really want another content management system. In your
opinion, what would be a good way for this person to set up and use
Open ID on his or her own server to post comments on, for example,
Live Journal?
Thank you for your time,
