John,

The solution to this is staring you in the face. We have great gobs of
unroutable / semi-routable IPv6 space within the 6to4 spec. If you
already have unrouted IPv4 space, why not use the corresponding
unrouted 6to4 space for your non-DFZ tasks? Each /24 of IPv4 space
maps to a /40 of IPv6 space or 24M subnets.

Bill Herrin
