In the long term, i'm rather convinced that an architectural change will
be required. I can't see other scalable alternatives.
But it's not all-or-nothing. Current common practises require
independence already -- at "largish ISP" level. This is deemed
acceptable, in contrast to late aggregatable global unicast addressing
(RFC2374) with hard limits. So, independence is OK to some degree.. but
we must not get that degree get too far unless we have measures to provide
