Openid Capabilities

My selection criteria for “Openid Service Providers”:

Needs:
Reliability:  As noted previously, an offline service provider is not one.
Multiple Profile/Role:  I serve multiple roles online and having to maintain multiple separate identities is troublesome.  I would prefer to maintain one identity with multiple views. (Verisign)
Delegate:  Being able to set up a web site with server capability through a single identity service – rather then configuring this capability on multiple web sites. (Claimid)
Aggregation:  Being able to consolidate multiple identities in a single view is going to be more and more necessary (Claimid)

Nice to have:
Identity through association:  Claiming (in a secure manner) web content and personal associations is nice – but not really what is necessary for me.

Anyone have any other criteria I should include?
