   I agree with the math, assuming the calculations were done
correctly. (I have no reason to suspect they weren't!) The idea that
everyone watches at the same time is a bit tough on the math, but I
understand your point.

   I think the alternative view is that my next NetFlix Watch
Instantly device will contain a hard drive. The movies will be
downloaded continuously, no 'On Demand' and become available to watch
when they are completely here. (Or a large enough percentage of the
movie is here so as to not need to worry too much about Internet
bandwidth.) I'll stick 20 movies in my Watch Instantly queue. At 4GB
it's 100 GB for DVD quality. No big deal. So what if I cannot really
'Watch Instantly'. It probably beats waiting for a DVD in the mail and
not really knowing what they are going to send me since they don't
always send me what's at the top of my queue. With this technology
they can deliver 'Be Kind Rewind' (releasing tonight, 6/16/08) to
1,000,000 homes without needing to own the DVDs, the machinery to put
then in envelopes, the people to run the machines, the Post Office,
the gasoline.

   Hey, a positive environmental impact! ;

   Granted, it is 4*10^9 bytes * 1*10^6 homes or 4*10^15
bytes/movie/day, but that's their business. They also receive
$15M/month from us subscribers to pay for it, right? They'll spread
that out nationally in 20 server centers and it won't be such a big
deal in the end. Comcast is apparently dropping fiber into my
neighborhood so bandwidth seems like it will be here pretty soon.
