Yes Bert, I covered this...twice now.
It is one of the major reasons the telcos are giving up on FTTH.

I covered this too, and the same for DSL.
Pay attention to my posts Bert

Pay attention please.
We are talking about what it will take to make the delivery of ALL content via
the Internet a practical reality.
If a home has three people watching TV at the same time, that is three streams.
This is possible today because most people are tuning to the live stream
portion of the cable system, not using broadband Internet streams. To get to
the point where we can turn off the live cable streams, we need >25 Mbps to
every home on the cable loop - maybe more if all streams are HD.

Yup. We are now talking about the same problem. To do this they need to have a
channel for each home on the loop, or at least a big chunk of a channel.
They are not there yet. As they deploy more risers they are getting closer. At
some point they will reach a theoretical cross over point where they could turn
off all analog and digital TV channels and use IP exclusively. They are not
there yet.

See above.
