Santo,

In general, to a first order approximation, I would expect a fully meshed arrangement of 'country' border elements. However I would see the fine detail of the structure being down to who people have arrangements for resolving addresses with. For example, BT might go to AT+T to resolve all North and South American numbers, and AT+T might come to BT for all European numbers. I could also see that opportunistic companies could set up global clearing houses that would handle address translation for outfits that haven't been able to establish their own knowledge of all the borders such as ISPs, or corporates. This would look like a root node to the people that used it, but it would be used purely as a commercial expedient and not mandated by the way the standard works.

On the issue of France moving its entry point to Lyon for the week, I think we have to allow France to have more than one entry point. After all, Paris could all of a sudden slide into the Seine, and the press, if nobody else, would still want to make calls into France to find out what's going on. By having multiple entry points, the French can turn off their Paris BE for a while and switch on their Lyon one, and if the data didn't propagate around the system for a while it wouldn't really matter too much.
