Sure. But it isn't an ISP's job to provide below-cost infrastructure
to subsidize the bandwidth requirements of Sony and Apple.
Pricing should be set without reference to the application developers.
If the application developers end up building applications which are
too expensive to use, then that's their loss. Nobody in the service-
provider industry should be going out of business because they
can't afford the infrastructure needed to give their AppleTV users
20 Gbit/sec ports when Cupertino comes out with HHHHHD Video
in a few years time.

Why can't you? We do it all the time. You shape to 64kbps, which is
more than enough bandwidth to run a SIP session with a low-end
CODEC. Phone calls still work, hardly anything else does. (performance
on a Virtual-Access interface with a rate-limit on it is way worse than
performance on a BRI interface without a rate-limit because rate-limits
lead to tail-drops, which spooks TCP very, very badly. So 64kbps is
actually worse than it sounds for TCP applications, but constant bitrate
CODECs deal with it just fine)

You guys seem to be behaving as if this stuff hasn't happened before.
No, you won't see "basic" internet on a couple of gig per month. You'll
see "basic" internet on 40 - 60 Gbytes per month, which is more than
most mortals use in any given 30 day period (like, ferchrissakes, who
needs 2 Gbytes per day, day in day out? Grandma certainly doesn't
use that much when she's checking her email...)

No, the two issues are completely orthogonal.
You're supposed to be a network operator, stop thinking like an end
user.

No, metering means the network neutrality debate undergoes gravitational
collapse, and caring about what's inside a packet turns into a total
waste
of time.
You don't need to care about whether a packet has been paid for because
you know that every packet has been paid for. That's what metering
delivers.
Why do you think the DPI vendors haven't had much traction outside of
Europe and North America? It isn't because the rest of the world can't
afford them. It's because Europe and North America are where all the
"unlimited" access services are sold, so they're the places where DPI is
actually needed. Would you need to spend millions with Ellacoya or
Sandvine if your customers imposed their own self-created backpressure
against P2P usage?
Again: Some of the significant economies on the Internet have done this
already. The TWC paper isn't trailblazing, and every issue you can
think
of to explain why it'll be horrible and won't work has already been
demolished
by real-life day-to-day business in other countries. You guys who are
behaving as if the sky will fall are going to have to explain why the
Internet
industry hasn't ceased to function in .au and .nz before you get on to
explaining why its collapse would be inevitable in the USA.
