I think the biggest benefit to RPs is to create a library that is robust and portable that would allow for them to designate which OPs they care about. This is what I was thinking about: 1. This library should be written in AJAX/JQuery to enable it to be portable across any browser. The problem here is that these libraries may be limited in alternate platforms like mobile - those cases may require a different library. Perhaps the JavaScript could be built in such a way that it could execute on the client or the server. 2. This library would allow the RP to pass in parameters to this encapsulated (but open sourced) library indicating which OPs it cares about most. For those OPs, the library will surface them as prominently displayed options for authentication. For any selected option, the library would know how to handle the authentication, whether it can read from a cookie, ping a service, or offer additional user screens. There could be multiple layers to this library, as well, that would then allow the RP to designate less prominent, but viable, options. 3. This library would need to be flexible enough to handle any OP for any RP. 4. This library would be very easy to drop on a page or app. The only real implementation would be to add the appropriate parameters for the designated OPs. I agree that Federated Identities offers issues that are very different than those found in the proprietary Facebook Connect approach. That is why building such a generic, black-box library will be so difficult. That said, it also offers the greatest reward. OpenID needs to have a single library that can be dropped into any RP and immediately offer a dynamic, effective and seamless UX. What would be the next steps to prototyping some of these ideas? What are the implications to the OpenID flow that you are talking about, Santosh? -Daniel (By the way, I am relatively new to this list, so I apologize if some of these ideas have already been discussed.)

That is, it may well work fine if you want to use a well known provider like Google or Yahoo, but it will fail if you want to use a custom OpenID. Indeed, in the discussions we've had, have the client hint to the RP which OP the user prefers seems like the most plausible way going forward. Additionally, if RPs add discoverable endpoints for registration/authentication/authorization/sign out, then the browser or other advanced client could deal with these interactions with a mire pleasant, forgiving, and appropriate UI.
