Hmmmm.... the authority could just be the primary key that the third-party signatures are over. I'm not talking about the current SKS keyserver network, but some still-to-be-created federated synchronizing service. That authority could also authorize no longer sharing a particular third party signature, I think. It might still circulate in the federated network, but any time it rears its head again it could get ignored by the revoked authorization (or more: authorization to revoke). "Ignoring" might just mean not offering it to clients even though it's still part of the federation for technical purposes. There's a lot of chance for misunderstandings here. I started writing something less ambiguous and stopped due to the amount of work :-). Cheers, Peter. -- I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
