Agree. But I doubt that's going to happen without some serious changes
to different parts of the protocol stack. Is that something we're
comfortable with?

3: remove addresses from all places in the protocol stack above the IP
   layer. If higher layers are unaware of addresses and the addresses
   follow the topology, IP can route around failures by changing
   addresses.
