Just look at the 2nd derivative of the output of netflow from the
customer, and detect when it is positive. If it is too large, kill the
connection. Can be automated.

Exactly. As an extra service (which I am sure the user will buy), or
let a local ISP (Joe's Internet, tackle and meat) with 100-200
customers take care of that problem. Joe can sell the bells and
whistles including support to the end user.

Internet access is a commodity by now (believe it or not) and people
will buy it like milk. I have close to where I live, even if it is
(maybe because it is) out on the country side, 5 different locations
within 10 km where I can buy a new chain saw, but only one 15 km away
where I can buy an ethernet patch cable. Here everyone already have a
chain saw, still there is a market for 5 different stores to have
multiple brands on the shelf.

_THAT_ is why people feel hopeless.
