I didn't say it can't be done, I said the people arguing for real time satellite tracking haven't even examined whether it is feasible. Iridium only has ~8Mhz of bandwidth, that is fine for a sensor platform that probably only transmits a couple of times a day, but could quickly run into trouble with constant positional updates from thousands of planes (especially with streaming of cockpit data recorders, as has been argued for as well). And the saturation of the Iridium network is not something that can be controlled without extensive re-engineering to enable QOS.
