What we really miss is an ADS-B low-cost variant for drones. Safety requirements are different if ones takes into account the unmanned characteristic of drones. Furthermore it will be a great exercise in solving the known problems with the existing version. The main idea of broadcasting navigation data is worth the shot to optimise even more the use of airspace. Without lives at risk technical iteration can be, at least in theory, faster. We need more IETF-style drafts and RFCs rather than classic standards (i.e that require often more than 10 years to reach the market) to see a clever use of such a technology in our daily-routine.
