I think the general idea of dividing ASNs into LEAF and TRANSIT categories is a good one. A method of determining which ASs need to know about a given LEAF AS is needed, and, I think a lot of optimizations may well be possible.
Like I said, I think it requires some additional thought and refinement, but, I like the general idea.

Then belay my 16-bit ramblings. I'm probably a bit naive in thinking a new attribute would be passed along by enough transits to be useful; an "adopt this incompatible protocol or become an island" approach may well be needed.
I still have to wonder if some leaf optimizations are possible. Perhaps an incompatible protocol would leave more implementation wiggle room.
