So this isn't going to be ready by 6 February, 2011?

Oh.
I suppose we'll have to keep the antiquated OTA and MPVD pipelines in place for special occasions like the Super Bowl for a bit longer.
Seems to me that if we must go to all of that expense keeping those old pipelines open just for a couple of uses per year, there ought to be something those pipelines could be used for the rest of the time...

There is some television that by it's very nature is appointment TV.
We all know that the "cloud" doesn't cope very well with everybody
trying to get the same thing at the same time. In other contexts,
it's called a "denial of service attack."

So, how do I watch the Superbowl?
I think you're referring to congestion over an ISP's network, if everyone were to watch live streams of the same program at the same time. There are measures that ISPs will no doubt be taking as time marches on. In this Superbowl example, the easiest solution over an ISP net would be to multicast (IP multicast) the show through the network. As long as the streams remain within an ISP's own network, this should be doable. And, of course, the bandwidth of these ISP nets is increasing steadily as well, and the number of servers deployed throughout.
This is the opposite side of the recorded content coin. What's easier to do for over a two-way, mostly unicast medium may be more difficult in the one-way broadcast medium, and vice versa. "More difficult" doesn't mean impossible, though. In spite of what the pundits and "our pundit" might have you believe.
