Boelter Hall (at UCLA, where the IMP is) is open now. 
This fall we largely do in-person teaching, the campus is full of students and 
visitors.

I surely hope so too.  When I tried to get my old yahoo email account back (I 
have only ONE), and ended with the same empty page.  Hope some yahoo people on 
this list listening. It is important to me I can get that email address back; 
some friends only know me by that address.

I agree here. So the mostly needed thing is some verification system.
Wonder what people think about this:  http://www.nanog.org/mtg-0706/

something one can start using *now*.
There was virtually no comment after the presentation at last NANOG.

I guess the old adage, "In theory, theory and practice are the

I agree completely.
In a private reply I just sent to Randy, I said "have you heard my

In (your) theory, your paper may hold up.  In practice, your  
definition of stub network is most likely considered wrong, and that  
likely shifts a lot of the assumptions in your paper.


But I also believe that there are a few common practical patterns that  
cover majority of reality.
We need to be mindful of diversity in real world but also capture  
basic common patterns (I'd agree that the paper perhaps should have  
said a few more words about the former).
