Why should ISP X pay to run a 6to4 relay that would in essence offer transit
for customers of other ISPs? And let's say that ISP X offer the outband
relay for its customers only, how would the packets come back from the real
IPv6 Internet to ISP X IPv4 network? Is ISP X suppose to announce a
de-aggregate of 2002://16? That would create a huge increase in the routing
table size...
