One thing that noone seems to have noticed yet, is that using TCNZ for transit in this way is virtually impossible due to the manner in which they route traffic. TCNZ use BGP communities to tag and filter, as did Clear before them. So ingress and egress paths are filtered at the exchange points. I don't know if Telecom have started using communities to manipulate traffic paths yet, but if they haven't, I'd say it's only a matter of time. The peering argument is a political one rather than a technical one. In my opinion, "unauthorised transit" is nothing more than a convenient excuse. If it did actually happen, perhaps they'd be better odd re-visiting filtering policies. Just my .02c worth :-) Cheers, Gordon
