Since a lot of people who post here sound like they have a lot of
experience, I thought I'd ask about an idea I had.
I read this article,
'Aussie Claims Copper Broadband now 200x Faster'
http://slashdot.org/article.pl?sid=07/10/24/1228200
and was wondering what people thought about this subject. Is there a lot
of inefficiency built into networking? Has it changed significantly in
the last 5 years or 10 years?

The cited report seems to be a self-serving PR piece. Quoting from the
article:
"It is claimed that the algorithms can produce up to 200x improvement
over existing copper broadband performance (quoted as being between one
and 25 mbit/sec), with up to 200 mbit/sec apparently being deliverable."
Since the industry has been delivering 1 Gb/s (1000 Mb/s) over
twisted-pair copper for many years, with 10 Gb/s solutions now emerging,
it seems that Dr. Papandriopoulos may be a bit "behind the power curve."

Not for long distances, though.
Cable goes up to about 1GHz, subtract out what TV uses and use an
efficient code, you probably can get 1Gb/s down it.
That would be shared among the neighborhood, though.
DSL at 18000ft, I don't think you are very close to 1GHz.
(Not having actually read the article.)

um
he was refering to copper broadband performance I took that to meen a
replacement for adsl/dsl which i suspect is going to be a big ask ill
belive 200x when i see the paper in the tech journals and when they
can demo this in thefield :-)

In say 20 years we have gone from 75/1200 bps modem
to 20Mbps broadband - a factor of 20,000. To my
level of technical understanding the 75/1200 seemed full
at the time. Clearly I was wrong. I certainly lean towards
assuming that there is a lot more to come.
