Sorry for that.
I put together these slides from top of my head in the plane. 

However, we should not mention all the changes. To make it simple and easy to focus on the important points.

I cannot get what exactly mean by this sentence.
Do you assume a environment where a mobile node with multiple interface can make use of routing information for address selection ?

Important point.
I knew that, but I could not find a space for that.
Maybe we need to add some slides to elaborate.

Not only enterprise networks, but for networks where multiple upstream networks can talk with each other.

The main changes are about the legacy host support. Support by using NAT66 to the wrongly source-addressed packets.
