I’ve been generally supportive of the idea of a government push to build a real high speed telecommunications network across Australia. I’m not sure whether they will get there with the social benefits intact but very early on it was clear that the wired versus wireless technology choice was a tricky one. I advocated a market design (yes, a market design) that did not specify technology by benchmarks and rewarded providers for connecting up Australians. The reason for not specifying the technology was because I think it is generally better for the market rather than the government or monopolists to decide these matters.
As a case in point look at this post from Robert Scoble. It discusses lasers, yes lasers, as a potential broadband technology that avoids having to lay down cables. I have no idea if this is feasible but what I do know is that if it is the NBN as it is currently being envisaged is not going to look too great a decade from now.
