Add a qdisc, add 2 classes (one for the user and one for the rest), give the
first class less bandwdith, use the fw filter to catch the marked packets and
put them in the first class, use a second filter (or in case of htb, make the
second class the default class) to put all other packets in the second class.
If you do that, you can control the traffic of the user like you want. You
can even let it use all available bandwidth, but if someone else wants to do
it, he has to wait.
More info about shaping can be found on www.lartc.org and www.docum.org. You
need the fw fitler and cbq or htb to create the qdisc and classes.
