Contention/Oversubscription maths

Hi All,Do any of you have any pointers on how to go about predicting usage for high-speed ethernet access?
I'm running 1GE links into buildings, and hanging many (100-1000) 100M customers off switches in the basement, simple enough.
I'm assuming ~300Kbps average peak usage per customer, but I can't quite work out at what point that number becomes more important than the fact that each user can peak at 100mbit (and that the backhaul is only access-speed * 10).
I'm well versed in the economies of scale of fitting 10,000 8mbit customers into 1GE, but this seems altogether a different beast to predict. If any of you have similar scenarios I'd be very interested to hear on/off list :)
Finally, what do people think of selling a 1G service with 1G backhaul (and potentially 10s or 100s of customers buying this service alongside n*100s of customers with 100M service)?
Thanks, adam.
