What makes you think that the winning public/private partnership proposals for each regoin won't deliver a better core network with much higher CIR per subscriber than Telecom's current core network?
I was mostly referring to the international bandwidth costs that being in New Zealand entail. Whether you put it down to lack of large amounts of competition in the international transit market, or to the fact we're a content sink a long way form our content is relatively immaterial.
However from what I know about core network design and cost of fibre, 10G interfaces (and higher), building a thicker aggregation and core network than Telecom has at the moment wouldn't be cheap...
