AAISP have operated a time-based bandwidth tariff for many years: http://aa.net.uk/broadband-prices.html http://aa.net.uk/broadband-prices.html 9am-6pm Mon-Friday is charged at 1.25-10x (ratio depending on the technology/broadband type) the price of bandwidth outside of this peak time. Granted, AAISP customers tend to be more technical and are willing to pay more for an clueful ISP.
