This assumes that everyone in the neighborhood *wants* that level of
protection, and that it doesn't interfere (outright or inadvertently) with
their social habits or livelihood.  The restrictions imposed by such
'protection' could force some residents to have to go 'outside the
neighborhood' in order to meet with some of their friends or customers (or
family).  Better that the Neighborhood Watch or local police instead
recommend (or even give away) a small, easy to manage burglar alarm package,
and provide easily accessible information on how to reduce your risks.

An ISP should pass all reasonable traffic to, from, and between their
customers.  Actively monitoring the network for patterns of intrusion would
usually be acceptable, and would be analogous to the police patrolling the
area, or being available to answer distress calls, without actively
controlling neighborhood traffic.

I don't see why an ISP couldn't recommend, or even give away a copy of at
time of sign-up, a good personal firewall product.  Many that have been
recommended elsewhere are only a few dollars and are quite passive in their
operation.  Co-branded copies of this software, much like the branded web
browsers a lot of ISP's hand out, are a win for both companies.

I'm getting weary of running into roadblocks while trying to implement
e-commerce or VPN solutions because an intermediary ISP decided to block a
particular protocol.
