The concept to sell foreign unlicensed data buffles me. While the delayed data network can be considered as a garbage collection, certainly the sale of real time data are subject to a license. The owners of such data are the owners of the aircraft sending them out. Licensing is one of the big revenue generators in commercial aviation. It would be naive to believe that AA, DL, BA, LH, KL and all the others let this go unhappened and Airnav would not be flooded by legal action within a few months. Not to mention security constraints, pilot unions, CAA, OFCOMs.. just o name a few. Lawyers are just waiting for something like this to happen. Users should expect that their prepaid fees are lost once servers will be shutdown due to copyright or security infringements.
