i'll write a post about this that's more in depth, but the fact of the matter is: content is no longer linear when it comes to the internet.  If 2 million people are going to watch heroes it certainly won't be at the same time.  it will be at their leisure, so the whole technical capabilities argument doesn't hold up.<p>the stuff that is livestreamed is a different breed of content.  think more along the lines of interactive sessions on ustream and jtv.  they haven't hit a 2mil simultaneous stream.  the engagement for each person is much higher on those sites anyway.
