Network end users to pull down 2 gigabytes a day, continuously?

It seems to me that multi-cast is a technical solution for the bandwidth 
consumption problems precipitated by real-time Internet video broadcast, 
but it doesn't seem to me that the bulk of current (or even future) 
Internet video traffic is going to be amenable to distribution via 
multi-cast - or, at least, separate and apart from whatever happens with 
multi-cast, a huge and growing volume of video traffic will be flowing 
over the 'net...

I don't think consumers are going to accept having to wait for a 
"scheduled broadcast" of whatever piece of video content they want to 
view - at least if the alternative is being able to download and watch 
it nearly immediately. That said, for the most popular content with the 
widest audience, scheduled multi-cast makes sense... especially when the 
alternative is waiting for a large download to finish - contrawise, it 
doesn't seem reasonable to be constantly multi-casting *every* piece of 
video content anyone might ever want to watch (that in itself would 
consume an insane amount of bandwidth). How many pieces of video content 
are there on YouTube? How many more can we expect to emerge over the 
next decade, given the ever decreasing cost of entry for reasonably 
decent video production?

All of which, to me, leaves the fundamental issue of how the upsurge in 
traffic is going to be handled left unresolved.
