RE: Can P2P applications learn to play fair on networks?

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.

"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?
