Traffic Shaping on DSL?

jackla asks: "I'm now looking for software to do traffic-control on my Windows XP box. I am connected with DSL and my upstream is capped at 96kbit/s (down is 1.5Mbit/s) - this means that high(>70kbit/s) upstream utilisation KILLS my downstream: it just drops down to about 400kbit/s and stays there unless there's more upstream space. That said, I read alot about the Linux shaping solution (wondershaper or something) which sounds exactly right, except I need something that works for Windows. What I want to do is prioritize upstream ACKs (for example) so that my downstream isn't affected by upstream use. If anyone heard of a peace of software that can do this, I would love to hear about it." It would be nice if something like this existed cheaply for Windows. I am unaware of such, but maybe a few of you have ideas. Could such a traffic shaper be built using low powered computers? If so, how would you build and configure it so it would maintain compatibility for the single Windows machine, behind it? (Think: homebuilt traffic-shapping appliance)
