Hi

I read through the latest "congestion exposure problem" document 

A few comments:
 
Section 5.1, last sentence in first para: "The main effect of this has
been that users now routinely see their network connections running slow
in the evenings"
>From a laymans perspective I can probably agree with this, I experience
it every now than then when I "surf the internet" from home. I have
however not been able to determine for sure if the problem is in the
network or in the webservers. I would believe that a reference to
scientific paper or mailing list discussion or whatever that describes
this problem would be beneficial.

Section 6 (Use cases):
Maybe obvious (and maybe does not fit into the use cases) but as I see
it the future results of this WG would be to provide mainly the
operators with at least one of the tools necessary to give e.g content
providers and application developers a 
sustainable "carrot and whip" offer. "Make your traffic behave according
to these rules and you're granted access to our network". I have no
opinion regarding what kinds of traffic this would include, I guess time
will tell, but the main task for the WG should be to provide with one
important item to the "carrot and whip" toolbox. 

PS.. Resent as the first effort looked like crap on the list
