My thoughts agree here much per start by defining the goals. The title
of net neutrality seems pithy at best os using that as a foundational
pier seems a bit off. Also, this group seems to have an excessive focus
on the CPE side and the technical. My thoughts are this is an economic,
legal and technical issue. The server side, app store access, etc.
matters too, and maybe even more than IAP/CPE side. We've already seen
the incumbents server side providers squeeze out traditional industries
like journalism, things required for effective representative Republics
per not sending any advertising revenue to these critical functions.
Where is the public service obligations around factual news in the
context of contract carriage communications?
A starting point for goals may come from the enumerated list per Noam on
common carriage
1. Reduction of Market Power
2. Assurance of Essential Services
3. Spread of Basic Infrastructure
4. Reduction in Transaction Cost
5. Limited Liability
6. Extension of Basic Freedoms - Personal and Commercial
7. Facilitation of Competition

Also, as the iperf 2 maintainer, I'm very interested in QoE scoring or
other metrics to help evaluate how well a network is performing, though
my bias is towards network engineers who can affect changes and less
about politics and economics. My take is that technology is improving at
quite a clip such that it's hard for most, even experts, to keep up.
(And we still don't have FiWi has the potential to help us jump from
kerosene to led lighting systems within a premise. Rather, we seem to
design for poorly constructed premise networks and apply congestion
algos instead of getting rid of or mitigating it.)
I think we need a new trade industry for modern communications
installers, mostly with skills in fiber and 802.11. These technicians
are as critical to the U.S. economy as our electricians and plumbers.
I'm thinking we should start by knowing where we want to go.
