Right. Thanks for explaining this so clearly. And I agree with Robin that mobility does not have to imply change of the tunnel router endpoint. This does reduce mapping changes. However, I'll note that administrative boundary crossings are quite typical even in situations where you don't move a lot physically. E.g., from my office to the city and then to my home; not far away physically, but they reside in very different places in the Internet topology. (In any case, what I am looking forward from the RRG or anyone who is working in this space is a solution to the routing scalability problem. I don't have a solution for that. I do have plenty of solutions for the mobility problem, however, some deployed some not. I have a hard time believing mobility is going to be the deciding factor with regards to a new routing architecture. Lets see a working routing architecture first. Just a personal opinion...)
