We have this kind of traffic data already running in a trial environment for about three years. Using push technology in combination with data from adsb-exchange and OGN we created some kind of “virtual atc”, what worked quite well. But because it requires a device with a mobile connection and a small inquiry arround a group of our users complained about this and the delay of ~15 seconds we decided not to put it in an actual release. Maybe worthwhile to reconsider ... 

it is true you need stable internet connection.

but it is still usable when flying in proximity of airports when you are close to ground and traffic is denser.

where can i find more info how to use this feauture? i would be happy to test it 15 seconds seems usable enought to know general direction to other traffic.

This feature isn’t publically usable, to be honest since we decided not to contiue with it it hasn’t had much attention. But let me check upcoming weeks, maybe its easy to  pollish it up and reactivate in EV4 when we port VirtualRadar.

I have programmed in python for android "virtual" flarm, that pulls data from internet and sends it via UDP to EasyVFR. Sometimes it works, sometimes it does not (internet...). But few times it actually warned me of traffic in front of me, so I still use it.
