Even admittedly with no evidence, I tend to disagree.  I think the world
needs cable-driven "mostly-one-way" Internet access for the same reason we
need both:

1.  Magazines/books (few to many) vs. snail-mail (1-to-1 communication).
2.  Television/radio (few to many)  vs. telephones (1-to-1 communication).

If, as I've heard, you could broadcast 28 mbits per second down a
6-megahertz cable line, that's a lot of "news, weather, and sports" to be
broadcast to EVERYONE, similar to newspapers.  Imagine the entire contents
of USENET,  plus a goodly supply of (encrypted) individual mail, etc.  The
contents of every newspaper in the country, transmitted a few times every
day, etc.

No idea.  Wish I knew.
