After mucking about for a while I have managed to replay the GDL90 I captured off the Stratux (onto the network) and feed it into my Godot app map. In theory, this would work in in the cockpit off the Stratux.
This live traffic replay is pretty slick. I think I'll integrate it into the app at some point. I watched my departure and getting vectored around some other aircraft on the map. I want to color code the aircraft by height (similar to adsb-exchange) too I think. It gives me an easy scan of how high something is.
