Hey Dick.
This is more on topic for the mid air over MNG but I have a little solution for inbound ADSB I am using right now. Its an RTL dongle, a raspberry pi and a screen. It runs gnuradio (built for ARM) and an HMI written in in python/tkinter. Obviously integrating a thing like that into an aircraft would not be completely simple but you could run it on a laptop and get good results.
One thing which I wish ADSB had is the frequencies being monitored by the aircraft. You could put that in the track label and know immediately how to make contact.
There is a wealth of information in ADSB but we are not really using it at the moment.
