The current routing model doesn't scale. I don't want to sit 5 years from now needing a router that'll handle 8 million routes to get me through the next 5 years of route growth.There is no way to do traffic engineering with any shim6-like system like one can do with BGP as shim6 is a completely host-centric solution. It has no clue about upstream/downstream/peering, ASses etc. Those things that actually make topology and economics. That's aside all the other administrative nightmares associated.
PI space for multihoming and AS number growth is a bad thing for scaling and economics, however you look at it.
Shim6 would hopefully curb the prefix growth very early in the growth curve as single entities won't need AS to multihome between two different ISPs.
I do believe in a completely new solution for multihoming than what we have today, shim6 is the first I've seen so far, I'm open to other suggestions though. Current way of doing it (AS+PI) gives me the creeps when I extrapolate into the future.
