Since the first meeting in Vienna there have been a lot more 
presentations. I didn't say anything about Minneapolis. Whatever.

Yes?

Yes? And if the end host selects an address that belongs to a TLI that 
has a internal network failure and the traffic is blaockholed in that 
providers network, how does the end node find out? TCP timeout?

I am not. But it's the multi6 WG that will have to end up selecting 
what to move forward.

"Guilty"!? Whatever.

So each TLI can have their own policy for their down-stream NLIs? Who 
decides who are the TLIs?

Actually, this is an issue today. Not a complex one, but there is 
policies in place for it. And if a TLI no longer is a TLI, that will 
have implications on down-streams.

Your draft does makes assumptions on how the policy would like. It 
actually makes assumptions that are very different from the model of 
today so I think it would be reasonable to explain the thinking. 
Otherwise I don't think to many ISPs will be interested.

What about TLIs that do have large customer bases in local networks? 
What about very dominant local players that today can force large ISPs 
to peer simply because of the dominance in particular markets?

Again, if you propose something that ignores the polices as they are 
implemented in todays Internet, I would expect at least some 
elaboration on how you see todays ISPs adopt this scheme.

It creates a nightmare for it's customers. Been there, done that, and 
have plenty of T-shirts to prove it. I think you miss the point. 
customers do not want to renumber if their _ISP change upstream_. That 
have a financial impact on them without them having control of the 
decision.
