There's a large "installed" based of asymmetric speed internet access links. Considering that even BPON and GPON solutions are designed for asymmetric use, too, it's going to take a fiber-based Active Ethernet solution to transform access links to change the residential experience to something symmetrical. (I'm making the underlying presumption that copper-based symmetric technologies will not become part of residential broadband market any time in the near future, if ever.) Until the time that we are all FTTH, ISPs will continue to manage their customer's upstream links.

Agreed. Measures, like NAT, spoofing based accelerators, quarantining computers are developed for fairly small networks. No for 1Gbps and above and 20+ sites/customers.
"small" is a relative term. Hong Kong is already selling 1Gbps access links to residential customers, and once upon a time 56Kbps was a big backbone network. Last month folks were complaining about ISPs letting everything through the networks, this month people are complaining that ISPs aren't letting everything through the networks. Does this mean next month we will be back the other direction again. Why artificially keep access link speeds low just to prevent upstream network congestion? Why can't you have big access links?
