Sorry if this was covered elsewhere, but if mbelib captures Opensky packets, and the DV Dongle (with AMBE vocoder) hardware and software is fully documented and available, couldn't mbelib use the DV Dongle to decode/monitor Opensky? Wouldn't this also solve the "patent issue" with the mbelib AMBE software decoding? (kudos to dsdauthor for your efforts to date!)
