Soon, but there’s not a scheduled time yet. Sorry!

In the meantime, there should be a workaround: even though the main Openid login form is broken, you can still use the “More options” comment form to log in.

Your friends can click reply on any public entry, choose OpenID as their user type and check the login box, and click preview; that should log them in without posting the dummy comment, and then they can interact as normal. Hope that helps!
