=> I don't know when this will happen. Non-NAT access is available
from some today. I'm not naming anyone though.

=> Several operators already have this.

=> You certainly have your own definitions :) I called them
home addresses. An HA may be administered to provide mobility
only within a single admin domain. There is nothing in the 
HA definition that mandates that it works globally. Of course
it can but admins can do whatever they want.

=> Point me to a spec that defines it this way and I'll
agree with you.
