Re: @DavCrav - take the road network for the UK.
Road metaphors are what arts graduates (like Al Gore) use to describe packet networking. Road is suitable for phone networks but not packet networks. There is no analogy for a road that dynamically reconfigures itself. The capital cost of a new dedicated toll lane has no analogy in multiplexed networks.
Sorry, but you are ignorant and have just proved the premise of the article.
