For me, plenty, but a four-POP single-state network usually has different constraints on "scalable".

I think Pete is saying that as long as you aren't a control-nazi, its a good system. :)
My point wasn't that his system doesn't work for him; presumably it does. My point was that in the context of global peering, what works for a small network may not (and probably does not) work for someone the size of, say, Level3. There are a lot of operational issues that arise if you listen to MEDs from peers. Apart from the "minor" issues like oscillations, ratchet-down, and packing inefficiencies, there is the fundamental problem that you will see potentially significant churn as a result of changes in your peers' networks. There is also the problem that there is no single "best" exit point for many large prefixes (e.g., if you peer with L3, there is no one "best" place to send traffic destined for something inside 4/8). --Jeff
