I just borrowed the name used in one of your posts.
I think bandwidth limiter is more discriptive.

I understand from Alan Cox that someone is already writing this for linux.
We shall see when it arrives.

Sadly. People have to make a living somehow though.
[Hey, I like free software, I use it almost exclusively, but
if I can't get what I need for free I'll pay for it.]

Sounds good. Is there any literature you can point at that discusses
exactly that your stuff accomplishes? If I can ever get FreeBSD to
boot on my machine I'll check it out. [I've been trying to get
FreeBSD to boot on and off for a while now. It would be useful
to be able to do performance comparisions between the FreeBSD
and Linux TCP implementations.]

I take it then that you need to make modifications to the networking
internals to make this work?
