OK, the idea is pretty simple. Rather like the "OpenID Authentication
Security Profiles" you have a profile where the RP states what kind of
End User/OP authentication is acceptable to it. Sites with low/zero
value attached to the login can accept any kind of EU/OP auth, whereas
high value sites can require "unphishable" auth.

Obviously some serious work is needed to flesh out this proposal, but
it seems to me it allows OpenID to stay lightweight (and phishable)
where appropriate, but also to serve a useful purpose for high-value
applications.
