Michael said the same thing "Also note that IP multicast only works
for live broadcast TV." and then mentioned that p2p could be used to
download content during off-peak hours.
Kazam is a beta test that uses Intercast's technology to download
content overnight to a users PC via multicast.
My point was p2p isn't the only way to deliver content overnight,
multicast could also be used to do that, and in fact at least one
company is exploring that option.
The example seemed to fit in well with the other examples in the
the thread that mentioned TiVo type devices recording content for
later viewing on demand.
I agree that multicast can be used for live TV and others have
mentioned the multicasting of the BBC and www.ostn.tv is another
example of live multicasting. However since TiVo type devices today
record broadcast content for later viewing on demand there could
certainly be devices that record multicast content for later viewing
