Your basic argument is that people really want PI space, and as long as the
ISPs continue to bias the RIR policies against organized PI space there will
be pressure for a grey-market in anything that can be used as PI. A
structured and manageable, non-swamp but non-perfect-aggregation approach to
PI is described in draft-hain-ipv6-pi-addr-07.txt. Comments welcome.
