OpenID anyone?

Hey all. I’ve been looking around for a way to implement OpenID for comments in WordPress and haven’t really found anything that’s past beta stages. The best one I’ve found is this one, but it seems to still be in beta. I also had an issue with some require_once()’s in the libraries that I needed to install, so I’m somewhat at a loss.

Has there been any more work on an OpenID plugin for WordPress? I’d prefer a plugin rather than a hack, but I’m interested in anything.
