not to be even more anal, but i believe broadcasting is used to imply over airwaves.
this thread is about web video, and a streaming server would enable "webcasting," no?
even the cable industry oftentimes calls their product cablecasting to refer to the non-over-the-air nature.
which brings us full circle to that old term "telecast." will that now mean video distributed for cell "tele"-phones over "some" band?
