Let's have a look at the current world wide bandwidth stats:
http://www.netindex.com/download/allcountries/

South Korea has the best figures in the world:
http://www.netindex.com/download/2,89/South-Korea/
which is 32.22 Mbps.

I feel the biggest bottleneck will be disk I/O speeds, but they will get much better over a period of time as SSD
technology takes over.

Cheers Don...

**Really? What's the bandwidth of fibre? 500THz? Higher? There is
considerable room for growth in a fibre network over the next few decades.

All new computers have gigabit ethernet.
The NBN is up to 100Mbs, or 0.1Gbps.

Although I am no fan of Billy the Goat (Bill Gates), I have to say that
according to the Wikiquotes site relative to Bill Gates I find this
purported attribution being refuted this wise under the heading
Misattributed:

* 640K ought to be enough for anybody.
- Often attributed to Gates in 1981. Gates considered the IBM
PC's 640kB program memory a significant breakthrough over
8-bit systems that were typically limited to 64kB, but he has
denied making this remark. Also see the 1989 and 1993 remarks
above. I've said some stupid things and some wrong things,
but not that. No one involved in computers would ever say
that a certain amount of memory is enough for all time … I
keep bumping into that silly quotation attributed to me that
says 640K of memory is enough. There's never a citation; the
quotation just floats like a rumor, repeated again and again.

They forgot to add the bandwidth equivalent of "PMPO".
When you specify "up to" you absolve your responsibility of actually
supplying that much.

Remember when Telstra was advertising their 12Mbit wireless USB dongles
a while back?
Before they even upgraded their network equipment that was capable of that?

I have doubts at all with the infrastructure they'll be serving out
will actually be capable of 1Gb/s AT ALL. After all, when they say "up
to", they're allowed to leave out the test conditions of a single user
per server.
Entirely unrealistic under normal use, but they're not lying because
they meet their test conditions.

Too bad the general population have no clue about what to ask, to call
them on their bluff...

As I was told by a Marantz sales rep some time back when quizzing him
on the usefulness of their 256 times oversampling CD player.

"People don't buy CD players, they buy numbers".
