TIme to leapfrog... and free up bandwidth from analog TV, other bandwidth hogs
Arthur C. Clarke (who gave us the math for geosynchronous satellites, thus has had time to think of that technology's implications) said in one of his nonfiction essays that developing nations actually have the splendid chance NOT to make the mistakes of more developed nations - like laying out millions of miles of copper and/or optical fiber for telecommunications - satellites are the natural mode of communication for places with more land than money.
If you're determined to drop a few billion dollars on a national broadband network for Australia, make every dollar count by saving the cost of physical transmission lines across the country. Instead, invest in a mix of satellite up and downloads between cities and townships, and/or line-of-sight microwave relays. LOS microwave worked just fine in my native state of Louisiana, where dry land is scarce and copper began becoming scarce as small communities wanted good quality phone service, and eventually corporate data connectivity to tie SCADA networks together, collecting production data on oil and gas wells, banking data and ultimately Internet connectivity.
Now that Hughes Telecom has point-to-point high-speed Internet satellite networking getting faster and faster, their corporate parent General Motors audaciously put satellite phone and data links on every model of their most modest automotive line, Chevrolet (the American equivalent of GM's Australian subsidiary Holden). Before this, GM had traditionally tested new and advanced technology on the higher-priced car lines, like Buick and Cadillac. Satellite data transmission is getting progressively cheaper - so why invest in all that copper and fiber optic for the NBN?
Of course, that's a rational question, and NBN is, like most political endeavors, likely to be controlled by a web of irrational motives. America sort of fell haphazardly into its web of high-speed phone and data network, shunning high speed fiber-optic lines until they became necessary to the cable TV and phone industries to provide progressively faster networks for distributing movies, hit television miniseries, and Internet games.
MMPORGs are driving a certain percentage of demand for high speed broadband, and I can't help thinking that as the demand for bandwidth to allow people to become their avatars increases, NBN will need to be just as fast as it can physically be. Moore's Law might be a quaint shadow of the mid 21st century's demand for bandwidth as more and more people begin inhabiting Second Life, World Of Warcraft, and other virtual worlds where players' experiences are limited only by their imagination. As economics contracts possibilities for people to have intriguing real-life fun, virtual worlds will increasingly be an escape from drab and nasty reality.
