I agree that data streaming for the so called "black box" should be done via satellite link. Typically, a data recorder catches about 4000 operational data every second. These data could be sent every, say every minute, via satellite link taking very little bandwith. I am sue that the AF447 and MH370 accident will accelerate the discussion on this feature. However, the agreement for this must involve a majority of countries. The best platform is ICAO.
