Wouldn't this be possible if ISPs throughout the world
installed a "reverse" looking Firewall at their
point of presence?

I believe that all broadband service connections
get out to consumers by going through a well-defined
access point, which feeds data bits out to subscribers.

Each subscriber has a firewall on their system to protect
against un-welcome "pings"

I think it would be possible for ISPs to
have a firewall at their point of access to their subscribers
that basically scans all upstream traffic aimed at the Internet
and "catches" anything that contains a Broadcast Flag Identifier

It would add a burden to the ISPs, who would probably
want to be compensated for the extra hardware/software/service
of "catching" Broadcast Flag Identifiers -
but, hey, Hollywood is a $30 Billion a year business,
and they could pay the ISPs to block Broadcast Flag uploads -

and Cisco Systems would probably LOVE to sell
upgraded "reverse firewall" technology on every router
they've sold to the ISP community.

Thanks!
