Name Data Network (NDN) concept gaining momentum
As far as my understanding goes, this is also directly the fundamental concept of the Maidsafe implementation of such an NDN based network. These guys take it further to a lower layer and bring it as a replacement protocol on top of the wires/fibres of the internet infrastructure.
Fundamental ideas about calling and connecting to data instead of calling and connecting to hosts (machines) are slowly exiting the early stages of academia and research and gaining more public impact.
Just recently Cisco and Verisign and a bunch of others presented some results to the public about a potential replacement of the IP (internet protocol) layer of the current internet generations with NDN.
