Hi all,

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?
