The difficulty as I see it is that our individual connections are
groomed at
the RAN into several large IP datastreams for feeding to netgate.

All of the accounting is done at the RAN, which is kind of early in
the
piece to be differentiating local and non local traffic.
 

At Canterbury to differentiate traffic between national and
international, they could really perform the accounting at any step of
the datastream. Each ip that you connected to, a reverse lookup was
performed on it and accounting done on the basis of it having a '.nz'
tld. There were problems with this, and as more and more New Zealand
companies decide to have a '.com' namespace, even though the servers are
housed in New Zealand, it will mislead the accounting process.

Aparently there's a doco somewhere which mentions all the ip
subnets/supernets that have been assigned to New Zealand. I would say
that instead of performing a reverse name lookup, that a lookup of the
subnet/supernet table be performed. This could already be what Saturn
do, no sure :/
