That was a refreshingly good post on this subject, Doc.

It also looks much more like a cable network. And
it's more compatible with a PON cable plant. I don't
know whether the PON is a common solution for IPTV or
not, however. Do you have an idea on this?

Makes sense. Again, this makes the IPTV and cable
plants look more similar.

Or, viewed another way, you move the in-home PVR just
a little further up the network. Out of necessity, in
part, because that last drop might not be wide enough.

And that's another example of how the different
networks will appear more similar. I would think the
cable-provided PVRs would perhaps have to be rethought
as well, for the same reason you mention. Or possibly,
each PVR can encrypt for just the one monitor
connected to it. Hmmm. But this would still be easier
to hack, being in the home and all.
So this is what I mean by "context." One cannot extol
the boundless virtues of IPTV unless one has a clue
of what the IPTV *and* the competing networks'
universes look like in reality. Not just fantasy.
That is what is sadly lacking in the trade press.
