Bob Frankston means Skype, not "Internet 2" represents the future of connectivity:
"It is useful to be able to understand how Skype works in detail in order to trust the code.
(...) The more important result is to understand Skype's Edge-connectivity. It's an example of how communities can stay connected independent on the accidental properties of the Internet and the gatekeepers.
(...) If the applications themselves are able to participate in finding dynamic paths we can start to move beyond the current Internet's single omniscient backbone that interconnects local LANs. The applications would find a path through a network consisting of way stations. "
