I agree with Atrocities. The world is not ready for the idea socially, the feelings of nationalism run strong (not that that's a bad thing) and each nation would be too wrapped up in it's own affairs to accomplish anything.

Thinking about it, I really don't think it can work as long as there are separate nations. Just look to the beginnings of the US government and transpose that to a world scale. Nation A would want more voice because they are more powerful economically, nation B would want more voice because they have more territory, and nation C would want more voice because they have more population.

Yeah, AT is right, it won't work unless forced.
