It's more about the business models that will fly at a given time. But on the technology front, note that as lots of traffic moved from really fast notebook computers to sort of slow mobile phones, the relative ratio of client to server power has shifted from where it was 5 years ago. No doubt it will shift again. That said, there is still far more going on with P2P today than there was 5 years ago - it's just less interesting to talk about than say SDN.
