Re: How does TSI offer unlimited? TSI has fairly high volume on Bell's side so they can afford to play averaging games... the average DSL subscriber uses less bandwidth than they "pay for" and that covers the balance of those on 25Mbps that might use more.
Pricing schemes are always about how to attribute cost recovery and profit-taking. With averaged schemes, someone always ends up feeling like one camp (low peak-hours users) is subsidizing the other but franking, I cannot imagine any indisputable way to divide the peak-hours bandwidth costs... it is one of those things where you just have to pick what you think is the path of least evil and stick to it.
