The real problem is that this technology is just in its infancy.

Right now, our TiVo's may pull in many hours a day of TV to watch.  In my
case, it's from satellite.  In yours, maybe from a cable company.  That's
fine, that's manageable, and the technology used to move the signal from
the broad/multicast point to your settop box is only vaguely relevant.  It
is not unicast.

There is, however, an opportunity here for a fundamental change in the
distribution model of video, and this should terrify any network operator.
That would be an evolution towards unicast, particularly off-net unicast.

I posted a message on Oct 10 of last year suggesting one potential model 
for evolution of video services.  We're seeing the market target narrower
segments of the viewing public, and if this continues, we may well see
some "channel" partner with TiVo to provide on-demand access to remote
content over the Internet.  That could well lead to a model where you would
have TiVo speculatively preloading content, and potentially vast amounts of
it.  Or, worse yet, the popularity of YouTube suggests that at some point,
we may end up with a new "local webserver service" on the next generation
Microsoft Whoopta OS that was capable of publication of video from the
local PC, maybe vaguely similar to BitTorrent under the hood, allowing for
a much higher bandwidth podcast-like service where your TiVo (and everyone
else's) is downloading video slowly from lots of different sources.
