Given that airportable ADS-B receivers are now reasonably affordable, is there a possibility of displaying this 'in' data on Skydemon - or is the facility already there?

Which specific receiver were you referring to? It would of course have to be natively compatible with iOS and Android, and have widespread market penetration, before we would integrate with it. We've already integrated with PowerFlarm which supports ADS/B in as well as Flarm.
