How do you build a new internet?

How do you cut online crime, tackle child pornography, halt crippling viruses and get rid of spam? The answers could lie in a £200m successor to the internet that computer experts are already referring to as the next rendition of the virtual world.Researchers in the US want at least US$350m (£175m) to build the Global Environment for Network Innovations (Geni), touted by some as the possible replacement for today’s internet. In Europe, similar projects are under way as part of the EU’s Future and Internet Research (Fire) programme, which is expected to cost at least £27m.
