He bills by the second or average hour like most people? It's not as black and 
white as it seems - you also get higher average when the number of 
connections increases, not just the bandwidth they consume.

I think you'll find that bursts are best counteracted like this:

This seperates 'downloads' from 'webpages', 'normal mails' from 'attachments' 
and you can then tune accordingly, if you have/get some graph.


Problem with today's modular software: they start with the modules
    and never get to the software part.
