Few questions about this plugin:
1. I see from the screenshots that the comment form becomes OpenID enabled. Is it possible to separate these two things? If I'm going to allow OpenID commenting, I don't want it tied to the "website" field on the form. Nothing annoys me more than filling in those blanks and then having some stupid website see that my URL can do OpenID and then instantly assuming that I want to do that. I'd much prefer a javascript approach where I can select an OpenID tab and replace those three fields with one field, or otherwise not automatically assume that just because I put in a web address that can do OpenID that I automatically want to do OpenID.
2. Login to the blog via OpenID: This is useless to me in its entirety. Can it be easily disabled?
3. Does the OpenID Provider code support the extra fields being sent back, like name and such?
