[OpenID] OpenID Identity Consolidation (Was: Re: OpenID based on email addresses... Just Works!)

[Chris Messina]

This is where Portable Contacts comes in, since we already accommodate
sending other known identifiers for a person.

I can't say whether it's wise to separate OpenID identifiers from
others, though, and I also don't know how well RPs will trust data
provided either via AX or PoCo (i.e. if a list of OpenIDs is provided,
will/should an RP take for granted that the list is a valid list of
verified identifiers?).

In any case, making identity consolidation/fallback account
association easier or more automatic is certain a good idea and a best
practice that should be better defined. I've started documenting these
ideas here:
