Do you have evidence to support the claim that 90% of issues occur in the
90% of the last mile that will be replaced?  My anecdotal evidence is that
the majority of the ADSL issues I've experienced occur in the pit outside a
residential property.  I don't claim my anecdotal evidence to be indicative
of the general population though.

One FTTN node per street or even a couple for longer streets) won't solve
the issue I've described above.

Is that the same as the original FTTP model?  Does the passive patching
frame become a potential failure point that didn't exist in the FTTP model?
 Does this add more complexity to the FTTP proposal which (as I understood
it) didn't use aggregation points out in the field, but rather ran a
passive fibre connection right back to the local exchange?

Today, yes, for the next few decades, not even close.  Why are they OK with
it today - because today's requirements and expectations are at least
partially defined by the capabilities that can be delivered to them today.
 I am sure that once the NBN is put in place, we'll move to a new era of
"haves" and "have nots" as the differences between what the technologies
can deliver are discovered.

Your Mum's email is slow to download because she's sending and receiving
things that even 5 years ago nobody would think of sending via email.  The
world has changed, dramatically, and continues to change dramatically at a
rate that is, frankly, quite scary at times.

We have to stop planning for today, and plan for tomorrow.

That's not even remotely fair.  In this world according to you, all IT
workers are highly paid or have low living expenses. and can easily afford
a FTTP payment of what has been suggested may be as high as $8k.  Not only
that, but apparently any person who needs more than FTTN can deliver in
their particular environment (noting that whilst VDSL with bonding can
deliver good speeds, speed drops with distance from the node) is likely
doing the wrong thing.  You might as well start suggesting that people of
certain ethnic backgrounds probably stole their computers...

Of course, small business, which makes up the vast majority of businesses
in Australia, has money lying around to spend on FTTP...

And I've added my 5c. :)
