FYI, Continental Cable (I think) already offers Internet service to regular
cable subscribers in some locales. Then there is the X*Press computer
information service offered by some other cable systems.
The Internet link has the capability to be much faster than a modem; it all
depends on how much bandwidth the operator reserves. With packet switching, not
much bandwidth would be needed to serve multiple users, at least compared to
the digitally uncompressed 6 megahertz of bandwidth needed for an ordinary TV
channel. It's the return signal from your computer moving upstream which is
most problematic.
I haven't heard any actual user reports on Internet via computer. The company I
work for installs metropolitan wide area computer networks on cable systems for
institutional use by businesses and local governments. We did one cable network
at Chicago O'Hare airport that had everything but the kitchen sink: Security
cameras, telemetry, computer data, phones, etc. Such technology is well
understood and very workable if done correctly. Running computer services over
a subscriber cable network is a bit different but not grossly so.
