There are many "reasonable" things providers could do.
However, in the US last year we had folks testifying to Congress that QOS
will never work, providers must never treat any traffic differently, DPI
is evil, and the answer to all our problems is just more bandwidth.
Unfortnately, its currently not considered acceptable for commercial ISPs
to do the same things that universities are already doing to manage
traffic on their networks.
The result is network engineering by politician, and many reasonable
things can no longer be done.
Fair usage policies
QOS scavenger/background class of service
Tiered data caps billing
Upstream/downstream billing
Changing some of the billing methods could encourage US providers to offer
"uncapped" line rates, but "capped" data usage. So you could have a
20Mbps/50Mbps/100Mbps line rate, but because the upstream network
utilization could be controlled at the data layer instead of the line
rate, effective prices may be lower.
But I don't know if the bloggersphere is ready for that yet in the US.
