The virgin/optus 3G service demonstrates
how it would be done. There seems to be
multiple layers of authentication. - the
modem would need to connect to the
network. The network owner does this.
Then Virgin does the authentication and
authorisation for apps above that - for
web browsing, kindle downloads etc.

If it buys off the shelf products for
its network, it is less likely to get
into trouble. Though wild promises by
politicians could get it into hotwater
[and smartmeters ;-)]

On reflection, the wireless would be
installed/managed by the NBN
or the end user. Otherwise the model
breaks as different services would be
available in different places.
There are a few diagrams in the concept
paper they have released for comment.
They use the terms POI (point of
interconnect) and OLT, AEB
-unfortunately the paper does not have a
