Maybe I am misunderstanding your response but if you substitute USA for Europe, you have this now. All without Google or ad driven revenue, and without the privacy issue. The GSM operators already know where you are via the phone. They have the presence info on you, so this too is solved. I still do not see the "Google" advantage. Maybe the US market is more in tuned for this type of model. Can't see it being much of an advantage in Europe and the rest of the world.
