Only throttle when limit reached? (Score 1)

What about throttling PSP traffic once it reaches say 80% of your total pipe size. Make sure customers are that this will take place and also make available to them the ability to see the pipe capacity (and current P2P level). That way they can schedule their big downloads in lower peakage times. The advantage being when you are throttling you may only have to by a small percentage of P2P traffic.
