"I can only have an imperfect understanding of what VJ is saying with Content-Centric Networking, and I am extrapolating some of what I knew him to have been saying in the late '90s." So you just made all of that up? If you'd like to see the actual points (which say nothing of multicast and doesn't proclaim "group security" to be scary and magical), check out http://video.google.com/videoplay?docid=-6972678839686672840 http://video.google.com/videoplay?docid=-6972678839686672840 It's about providing network access to everyone from mud huts in villages to gigabit connected apartments in Tokyo. It's about making networking with content retrieval work over any medium, anyplace, anytime. It's about being able to drop "a box of Internet" someplace and having reasonable access to content. We could have a workable solution to what Van Jacobson describes now, but mobile devices and most computers are still too caught up in privacy and network lockdown. Being "connected" doesn't mean just having Internet access. It means being able to connect to everything around you and interact meaningfully without having to go through service providers and gatekeepers.
