I don't know. I use to drink tea, so perhaps a person more experienced
with coffee can help us out here.
(There is some rumour, that there have been central coffee machines in
some academic institutes in Stuttgart, but I don't know for sure....)

At least, our chancelor, Dr. Merkel, does not serve those streams.
Angela Merkel typically attends the game in the stadium, and when there
happens something interesting, she jumps up and claps here hands and all
TV stations send the picture of rejoicing Angela and she is frequently
recommended as the ideal coach for our national soccer team then.
To my knowledge, this is called "emancipation".

For some years now, we have something called "public viewing", where
some thousands of people (outside the stadium, bars and appartments)
share a common screen.
And a common toilet.
Perhaps, that's what inspired to think about congestion control using
"fluid flow models".
But I'm afraid, we're getting off topic here ;-)
(Didn't Michael talk about _flow_ control? ;-))
