Is anyone actually USING IP QoS?

Some assume, some do something to make sure it's going
to be like that :)

I know at least one company which is going to be in
field trials this year with the technology which can
actually handle traffic in case if every household in
US gets a T-1.

1000%/yr sounds like BS.  200-400% is more like it.
Reality check - see how backbones grow, not what
marketing people say.

Never underestimate bandwidth of 1 sq ft. bundle of
fibers.  Even if no advances are made in WDM or
femtosecond optical valve technology the petabit-per-second
networks can still be built for cost comparable to
the cost of POTS.


PS      Trend-wise speaking, backbones are catching
	up with host performance.  Before long, hosts
	will become the bottleneck, not the network.
	After that, network growth will follow the
	same trend line as hosts: i.e. Moore's law
	performance increases with pretty much fixed
