On the other hand, it's (in theory) a less painful problem to solve, in the
sense that any solution can be deployed on an Autonomous System (let's
remember the import of that term) by AS basis, rather than potentially
requiring system-wide coordination.

I don't have any 'off the top of my head' technical reaction to this point.
Let me ponder it for a while...
