So, what we need to come up with then are some clear benefits.
Removal of NAT is a negative - it may be better to say "true end-to-end
connectivity" and explain that?
Other benefits that I'm aware of:
* Natively integrated autoconfigure - lowers cost of management.
* Integrated IPSEC - tighter native security.
Am I on the right track?
