title: Is Windows Live ID an OpenID Provider?
body: <p>I've heard different things.  Seems like Microsoft <a href="http://winliveid.spaces.live.com/Blog/cns!AEE1BB0D86E23AAC!1745.entry" rel="noreferrer">experimented with a beta service</a>, but I don't know if it's still available, or ever made it into production.</p>
  
  <p>If Windows Live ID is an OpenID Provider, where is the endpoint?</p>
