I believe all the pure endpoint-based solutions scale routing by
making all addressing hierarchical.  Endpoint-based solutions,
including multipath, still generally expect an endpoint to know its
many addresses, and when a site changes its upstream connections it
needs to reconfigure all of its services and ACLs to deal with the new
addresses.  Ouch.
