Traffic shaper

I've been using cfosSpeed, which is a traffic shaper. I've been searching for something like this for quite some time now, but I never found any software to be quite what I wanted. Basically, I wanted a shaper that would be able to prioritize my HTTP traffic so that my browsing would not be affected while a download was in progress.

cfosSpeed seems to do that, and it seems to get me a faster response while browsing even when there are no downloads going on in the background. They claim better responses for online gaming, VoIP, and other such applications, but I haven't tried that out, and I probably won't. All in all, a good bit of software - it's shareware and I might just end up buying it at the end of my 30 days trial.
