I think what people don't realize is the role Cisco played in this trend. I don't mean to be all "rah-rah... my company is the best" and all (although I am in PR... so it is a bit of a reflex action) but if it wasn't for broadband and the increasing presence of the Internet in our lives, Slivercast wouldn't be possible (nor would YouTube... which is awesome IMHO).
I'm probably not going to tune into Sail.TV because sailboats make me throw-up, but I think it is great that people who want all sailboats all the time now have a place they can log onto and get virtually seasick.
And all this is because of the Internet... yay Internet.
