RE: ND-proxy applicability and loop-prevention




Pekka, 

I think you're oversimplifying the following issue:

=> I think it's a bad signal, _if_ detected. I.e. An average
user is not even going to know that they have 100% link
utilisation. And _if_ they do, I actually think that neither
the user, nor the help desk first line of support will
have the faintest idea (having been a regular with help
desk people that work for a couple of major operators
in different countries).

=> So if I somehow get inspired or guess that I should 
remove the proxy and things work, what does that tell me???
Maybe the device is faulty? Maybe I'll take it back to the 
shop! There is nothing intuitive about that from an average
user's perspective.
