Glad you think so, Matt. [On the question of a useful scenario for OpenID in the enterprise]
I think Pam misunderstands something about user-centric and the enterprise, however: Of course, the technologies built to support user-centric identity (like OpenID and CardSpace) can be used in many different ways, many of which aren’t user-centric at all. (I will always remember Rebecca MacKinnon’s remarks at that first Harvard/Berkman identity workshop.)
It may also be that many enterprises couldn’t care less whether or not a technology that they deploy is user-centric or not. And certainly, the enterprise’s primary objective is to increase value for its shareholders and other stakeholders, not picking between philosophical approaches to technology.
But what’s important here is not to forget that a certain new set of identity technologies has been designed specifically to support user-centric use cases. Which is new. And which makes them the technologies of choice for those enterprises that do want to empower their users, and they most certainly do exist. Not because they like one philosophy over another; but because user-centricity makes business sense to them.
