we are in complete agreement of the end goal. it is just how we get there...

issues I have with host tunneling:
 - how to communicate with native IPv6 nodes on the same network?
 - how to communicate to another 6a44 host on a different link in the same home?
 - do you need non-congruent topology multi-homing policy?
   http://tools.ietf.org/html/draft-troan-multihoming-without-nat66-01
   how do you distribute that policy when you don't have a on-link router?
 - a general unease that now every host is supposed to have a "VPN" connection?
   how do I configure my own firewall and other network border policy?

how much would a new CPE cost the customer? 80USD? that's only 5 pints of beer (if bought in Norway.)
I really liked the dongle idea by the way. perhaps with a L2TP LAC.

cheers,
Ole
