[OpenID] OpenID as a PKI facilitator

So then where are we placing the user's key?  I thought what was being
proposed was using the signing key as the user's public key.  Seems this
isn't the case, so then is the user's key going in as a DNS record (and
then in what format)?

What? There's no need for them to be using the same key if they're in
the same zone. The key that is the same is the one that signs their
records, i.e. the zone key.
