I'm sorry -- slip of the keyboard. Where I wrote "load-balancing" here yesterday (not once but twice), I should have written "traffic-shaping." I have only one Internet connection -- that's all I can get here -- but traffic-shaping moves the queue from the ADSL router or the ISP into the little Linux box, where it can be managed better, and ensures that heavy users such as big uploads and downloads don't crowd out interactive users. The Web search I suggested will make more sense in that context!
