[OpenID] Migrating User Identifier URL re: Connect

[John Bradley]

RPs can and do  link multiple ID to a single account.

You want some sort of automatic account linking hint for a RP so that if it supports that it can add other claimed_id to your account?

That is probably doable.

I don't know that we can require RP to support account linking.   

I suspect with connect they will probably wan't to have access to more of your social graph,  so will be encouraged to support it.
