Subs eh - this is some one with a trivial knowledge trying to apply one model (dns) to another (POTS). X.500 was the proposed solution (70's/80's) where you had interconnected directories that would allow a distributed worldwide directory to work. Only trouble is that a full working x.500 system is probably still at the bleeding edge of what is possible. A Google or Microsoft could do it if they upped their game in terms of rigous adherence to standards by a few hundred % or so. Stick to the frocks hunni.
