Just to explore this a bit: Presence or absence of 'trust' is orthogonal with /what/ is trusted. At small scale, long-term operators know each other and know both the what and the whether. At larger scale, they might develop a degree of trust through history but not have any way of knowing what the other side's signing policies are. For reference, I think this topic is likely to be unproductive, given how poorly concepts and practices of policies like this seem to fare. But it seems interesting, gets raised periodically, and at least could be a cleanly-handled topic if pursued this way. (Especially if it is encoded as a separate header-field...) d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
