This always true - even in the more traditional world of television
delivery (witness the recent removal of several Sky channels from the
Virgin Media line up). I'm not sure how much this is relevant to
your point.

No it doesn't - and I didn't say it did. There are various ways to
do that already out in the market. Some are for instance based on
set top boxes.

Sure it does - my entire point is that your average Corrie viewer
(like say, my grandmother) will record it on her set top box *from*
the multicast stream.

I've not bothered with Boingboing since they published the ridiculous
story that a UK user was arrested for using Lynx to access a Tsunami
donation site.
In any case it's still irrelvant to the inital point of the discussion
- there's still going to be a very low percentage of traffic exchanged
accross the phone exchanges.

You have figures for this - preferably properly researched ones - that
show this is actually the case as opposed to being simply a figure
paul pulled out of the air to try and back up a weak point.
In any case, even a 10% saving on link capacity isn't much[1] - the
savings will quickly get eaten up by increased traffic volumes. I
certainly know from having been there that if you are running an
STM-16 and you're worried about 10% of the capacity - then it's time
to get that link up to STM-64.

And because presumably part of the business model requires eye balls
on the site - a requirement that isn't going to go away. I doubt
very much that "significant parts of the network have been hidden" has
anything to do it - especially as from YouTube's POV they don't care
how the ISPs move the traffic to their users once it enters the ISPs
AS.
Of course, they almost certainly run some kind of distributing caching model.
