If you want to see swarmed downloads in action, check out Xolox (while you still can!). Swarming is really an awesome thing, and you can <b>potentially</b> max out even a fast cable modem connection if there are enough mirrors of the file you are downloading. Each person only sends a little bit, and the user gets their files many times faster. This may take up several other user's upload slots at one time, but they are subsequently freed up in a few minutes, as opposed to sucking from a single node for hours on end.
