Postmodern research issues
1. Money flow - how to get money to flow to providers that will inves in infrastructure and new services?
2. How should we build applications to take advantage of new services offered by the network? Can't ask (human) users, applications may not know their requirements, especially a priori. How to allow expression of policies for, e.g., choosing among paths? There are applications that know how to do this -- cf. protocols for video streaming.
3. Performance - how do we add the things we need (motivation, accountability) to the forwarding operation without destroying performance? This is a question about engineering the fast path, but may also have to do with amelioration strategies - e.g., are there ways to avoid doing it in certain cases?
