Its a bootstrap problem though. You have to establish the market conditions to favor multicast deployment.

They have not been right for general adoption to date. But as you point out we can reach a state where the incentives are right for the isps.

As others have said, this time 500k people (out of 750k) really wanted 
to view this at the same time...

I completely agree with this. Caching/storage etc of video and other 
distributed data have during the years moved closer and closer to the 
end user (consumer of the data).

At first, we only had direct transmission of TV. Directly from the TV 
camera to the viewer. Then we had caching in the form of tapes at the 
TV channel. Now we have DVRs at peoples homes, which imply even TV 
series that are produced long in advance could be distributed 
beforehand and cached on peoples DVRs (encrypted -- so at the time of 
the "live" transmission, the data is unlocked). How many things/hours 
are actually live, *really* live?

And this "pre-distribution" could be done over IP-multicast.
