Today's NBN politik comes thanks to the IT Wire:
"Mr Ballantine today argued that for most of Australia’s geography broadband delivered over satellite would be faster and cheaper. What was right for the city he argued was not necessarily good for the outback."
Maybe for download throughput, sure. But latency plays a huge part in satellite (and 3G style solutions) and it will be noticable.
Satellite IP doesn't scale. Sorry guys.
