@xdude have you considered looking into NetBalancer? The way the program works and looks it is exactly what you are looking for. It shows bandwidth usage for all processes, you can throttle processes or even your system as a whole. The free version is probably enough for what you want to do. I have been using it to throttle my system as a whole when downloading but wanting to leave some bandwidth left for other users of the network to watch Youtube and etc. Worked well.
