I don't know if you have noticed, but Proxymus does support shaping as well.
I do agree with the point that Amos made that users should be entitled to do
whatever they want with the bandwidth they are paying for, but in some
cases, like the country I live in, you must do some compromises as well,
mainly due to the high costs of the International bandwidth. You want to
maximize the utilization of the resources available.

This was the main reason we have made this option available in our product,
to combine the best of both techniques and more. I say more, because with
Proxymus you can specify the periods when you want the shaping of the input
traffic to be enabled and when to just let it go.

Also, if you have enough bandwidth, you may set the limit high enough as
well just to set a threshold that you don't want P2P traffic to cross. Like
a safeguard from a sudden burst of traffic.
