[e2e] administrative domains and the network layer

The issue of administrative boundaries has, IMHO, indeed led to some of the 
end-to-end "violations".  However, in my (limited) understanding of IPv6 I 
thought that the provider-based prefixes coupled with proper 
autoconfiguration should solve most of the routing issues as well as the 
renumbering issues.  Multihoming remains a problem.

I am not sure how the autonomous system concept would help the multihoming 
issue, since in that case the "autonomous system" describes the upstream 
provider, which is different for the two paths out of the users network.
