Expensive Investigation? Better Operating Alternatives?

What are the costs now being incurred by Brazil, France, Air France, Airbus and all other parties to the AF447 disaster? Ever thought of that? My estimation is that more than $500 million will be spent in the next 2-3 years in operations related to this mishap.

I wonder what would be the costs for Air France and other airlines of keeping the requested and cleared flight paths for scheduled flights clear of areas of massive convective thunderstorms, by using real time satellite photos, dispatch reroutes and various satellite and HF communications? By the way all of the technology is on board the airplane and in flight control dispatch offices.
