I agree about scope.  Though the client might reach different conclusions about what of that scope they want to use. :)

The authentication question seems like it might depend on context.  If you think of an HTTP server that says "use this resolver when you talk to me if you like", then that authentication might be implicit.  But Tommy's presentation relied on authentication via DNSSEC for some sort of delegation record.  That seems like it might not be explicit.
