So, are you saying:

I think what Alex is trying to say is pretty much make every router a confederation sub-AS of its own. That way, you never talk BGP with a router you're not directly connected to, so you don't need loopback routes to find BGP peers. If you then configure next-hop-self on every session, you don't need "redistribute connected" either so you've eliminated the need for an IGP.
And that: you don't use "closest-exit" at all, but haul traffic, wherever, around your network based upon steps below the igp-metric step in the bgp decision tree?
That's the part I can't figure out without some lab time either, but obviously you can tweak this setup to _statically_ do whatever it is you need, the only question is what happens when something goes down.
I'm sorry, but so far, I'm not buying how a static net is better.
"No IGP" doesn't mean "static", "no IGP" really means "no IGP". :-)
