yup. that's the design of the system. and by the way, in terms of DNS management, a selector is a sub-domain name, so it's the same administrative effort as a subdomain for d=. > I'm not sure why using the selector would be a bad idea, that would imply a new reputation to be developed each time a key is replaced (and therefore a new selector is assigned.)
