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 on demand. --- Bruce Curtis [email protected] Certified NetAnalyst II 701-231-8527 North Dakota State University _______________________________________________ NANOG mailing list [email protected] http://mailman.nanog.org/mailman/listinfo/nanog
