Before someone confirms or denies anything there's a simple question to answer:

Assume that you have an identity-something stored in a cookie bound to "myid.com".

How can this be utilized except by the user explicitly telling sites
that they have to reference "myid.com" (technically through an IFRAME
published on "myid.com")?

I don't see how this can be done unless the number of identity providers is
very low or the user types the domain.  For some people this is probably
OK, for me it feels more like stone-age.
