Just apply on openweb.co.za and wait a while to get an account... you apply on the forums section by the way and you have to register first. This proxy works great for Limewire and Kazaa (very easy to set up) but i cant get it working with DC++, maby sockscap can do the trick?
And no, there are P2P apps that arent shaped on Iburst, eg. ****** (done for our own good) but the problem is that there is no multiseeding, so downloads are limited purely to one users upload speed, but you can acheive like 800kbits if you download from a few users, just has to be diffrent files though. Problem is that its not very good for anything except music and some video. Also heard of another P2P that was unshaped on some other forum... cant remember though, but they do exist, theyre just crap.
