I think we are in violent agreement.  What I think would be good is to
not force anyone to use a "path" UNH-NRL-WIDE if they can go to
MIT-UNIVARIZONA-WIDE. It should be open to what path is available like
on the Internet today based on some metric of choice.  I also think this
gives us a better system test scenario and hopefully with ripng.  I
think it should be loose, complex, and break so we understand where it
breaks. Too much order in the beginning will cause us to get secure in a
bogus way.

No.  I am running your architecture why would I want that.  No one knows
it better than you.  I am just saying that the discussion of how maybe
to automate the tunnels should be OK.  The reason I brought it up is cause
I saw the problem if I had to do this for 1000 nodes.  In addition it
affects the transition.  When you speak as above its clear, precise, and
99% right.  But thats not what I heard in all the mail.  I heard people
who are not Steve Deering, or Brian Carpenter, or Christian Huitema, et
al. (who I consider people I automatically listen too) tell a person doing
this work and who themselves I don't think are even putting packets on the 
wire that, the other person does not have a clue.  Anyone in that
category should not shut up but I am not going to listen to them. OK.
I can see how you got what you did out of what I said and I am sorry
about that but that was not my intention.

I agree.  But I am not going to just sit here and watch abuse either,
and you know I can't do that even if I wanted to.
