I like the possibilities of XRD or even configuring a browser with a specific preference that it could "push" to RPs. It doesn't seem like it should be that hard for a browser to add a header with the preference or better, detect that the RP wants the preference and only send it when needed. Similar to how the Identity in the Browser flow discovers RP meta-data.<br>

That being said, adoption would be a much easier proposition if RPs hard better tools to identify the user's preferred IDP (or set of IDPs). We should seriously think about more direct broking of user IDP preferences via XRD discovery and/or a centralized service (which could be distributed among different organizations such as DNS to avoid over-reliance on a single player).<br>
