Use of the same (known and working) technology without extra global 
routes (assuming that the ISP has a "normal" prefix in addition to the
prefix used for 6rd) and without the mess created by not-really-working
6to4 relays and asymmetric paths.

With 2002:: in use inside an ISP, packets from 6to4 aware peer hosts out
in the world will be encapsulated into IPv4 at the sending host, and
then travel over potentially broken IPv4 paths, instead of travelling
natively IPv6 up to the ISPs relay...
