On this, we completely agree.

On this, I'm not so sure.  I think the changes don't need to be all that
radical, and, I don't think we need to split LOC/ID except in the
interdomain context.  I don't think prefix-based routing within an
autonomous system is all that unwieldy.

On that, we agree.  Personally, I vote now.
