Internet 3.0?

Techworld had an interesting write-up today on some plans that are in the works for a new version of the Internet. From the article:

The US government department that created the Internet is working on a new network that will be able to configure itself, intelligently cache and route data, and allow for fast and reliable sharing of data, all while maintaining military-grade security.

Government, corporate and academic researchers are all working on the project, called Knowledge Based Networking, that is under development by the Department of Defense Research Projects Agency (Darpa).
