So, if I get you right, you are saying that edge routers have fewer CPU requirements, and so ISPs can get away with software routers and don't care about FIB. At the same time, folks in the middle are saying that in any event they need to buy high-end routers, and so can afford to buy enough hardw

Certainly in principle it can, though that is not in the current proposal. The basic idea is to suppress installing routes into the FIB when there is a "virtual aggregate" that you can tunnel to instead. I remember we discussed this in San Jose NANOG, but I forget the details. Can you remind me?
