This is shtuyot bemitz. If you're gonna hog your internet link, you're
gonna hog, NAT or no NAT. If you're not gonna hog, you're not gonna hog,
NAT or no NAT. It depends solely on what you like to do with you inet
link - read mail or run a background news client downloading DivX ISO
movie images or compy games 7 days a week around the clock. (which a few
of my friends do by the way and I believe is a very widespread phenomenon)

If you take some ISP's 100 users and have them install home networks with
3 computers apiece with NAT, they will not change their hogging or no
hogging routines. They will NOT behave differently because of the NAT,
and they will not generate more traffic. They'll use your bandwidth the
same with or without the NAT, and three users hogging via NAT from one
ADSL connection don't generate more traffic then one user hogging his link
alone on a similar connection. Furthermore, as far as the ISP is
concerned, there is *no difference* if mom reads her email at 18:00, dad
at 19:00 and janice pumpkinpie at 20:21, as compared to them all sitting
together in the family computer room, each at his box, and reading email
simultaneously at 19:44, because dad is a compy geek who writes device
drivers that work with cat, and simply MUST have a computer for everyone
at home, dog included.
