I don't know PizzaClown........ What I'm understanding here is that let's say Tiesto tweets and FB's his followers to watch him on the webcast while he's performing, MPIX will participate and gets paid for every 1,000 hits. I think Tiesto has over 17 million likes on FB. No idea how many Twitter followers. Every performer has their own following which they'll hopefully also participate in this webcast and direct their fans to.
This is the link any one should be using for that webcast:
