The UK Federation for Access Management is up to 618 members (http://
www.ukfederation.org.uk/), and they're working very hard to ensure a
consistently good level of practices and trust throughout. It's
truly multilateral and a high level of assurance, and they've done
excellent work.

This is no doubt true, but I think that Yahoo, Microsoft, and Google
offer a very different level of trust and verification with their
email accounts. They've got a business to run.

Shibboleth's SP design is more at work here than anything protocol-
related here. The SP is built to protect resources and paths
directly, like a filter, with very little to no modification of or
integration into the application. As far as integration with the
operating system goes, if CardSpace rises from the grave -- four days
too late for that metaphor to be good -- then we'll all be in good
shape regardless. Microsoft's new Geneva identity suite will
probably offer a lot of integration, with all the good and "aaaargh"
that comes with that.

I'd like to remind people to focus a little less on protocols we use
and a little more on trust structures. OpenID as a protocol couldn't
support these trust structures today, partially by design; that could
change in the future as the set of deployers changes. Today,
Shibboleth is, in my incredibly biased opinion, a fine choice for
your application that requires trusted identity from known sources
and privacy for your users.
Thanks for the interesting anecdote,
Nate.
