Hi Christian,

I'm okay with your first two points but the third makes an assumption
that might not be warranted. You do need a trust relationship but it
doesn't necessarily need to be between edge networks. The trust
relationship can also be from the edge networks to one or many
third-party address authorities.

Also, note that item 1 can be achieved through a standard push-based
IGP like OSPF given some form of AAA system for the client.
