Correction re Telstra cable modems

I'd like to say sort-of the same thing, but a bit less pejoratively...

Ordinary users read more than they fetch. more time is spent not using
the net than using the net. "power" users might exceed that norm, people
doing internet voice or downloading big files or live media, or playing
doom over the wire.

Publishers of content and ISP's saturate links. Any ISP will tell you this and
some price sold on service accordingly. There is *NO* aggregration opportunity
in selling data to people who will use all their bandwidth.

I think Telstra have modelled this on home use and excluded SOHO. I don't
think they have considered a market niche who want to use 2-way bandwidth in
a concious sense. Now what I understand of HFC internet is that a "cell"
in some sense (a run of cable? 2000 houses?) is an ethernet. If this is
true then they *need* that scaling knowledge to be able to offer deterministic
datarates to people. If they have given you a 192kbps return channel
and 200 of you work for XEROX and get conned into SOHO then their net melts.

If the cable owner was a state monopoly and content was sub-let to competing
companies, I think we'd have seen a bi-directional product in the equation
much sooner. I Blame the gommint and agree with Kerry Stokes on that one.
