Hey, Xará.
I don't even want to jump on this whole discussion, because this is all has been said before. I want to put just a little note about this:

There is no such thing. I've never been given good space on conferences because of my MVP status. So far, I've always had to deserve my spot, by submitting good session proposals, and good evaluation from the presentations I've made. When submitting proposals, MVPs normally go through the same process of anybody else sending papers to conferences. Of course, being an MVP is a plus, but it doesn't directly affect the decision. And again, Microsoft DOES NOT give MVPs what you are suggesting.
