This table shows the varying degrees of support by a few OpenID providers, both in terms of OpenID discovery and the OpenID protocols themselves. You may hover over any of the protocols to see a little more detail about them. The small "x" link next to each provider is the OpenID URL I used for testing. Protocol support is based on what is advertised in the published XRDS document, but have not actually been tested. If any providers would like to be added to the list, please let me know.
Full Disclosure: I currently work for Vidoop which runs the OpenID Provider MyVidoop.
See my post about it here.
