Sim based server connection

I enjoy nothing more than flying in and around crowded airports and seeing other simmers flying. While I could log into IVAO or VATSIM and get this, I don’t always want to interact with ATC.

Would it be possible to develop something that would automatically switch the active server based on the aircraft location and not the physical location of the user?

For instance we could use longitude and latitudes to define which server will be activated therefore making all active simmers visible to each other given their airport.
