Combine frequency selection with streaming source (Real live ATC + AIG + Realtraffic)

I have Realtraffic/PSXT running with AIG. Then I use VLC player with adding a delay of 45 seconds. I am running multiple instances of VLC player for clearance delivery, ATIS, Tower, Departure etc. Of course I can only listen and not talk and need to somehow slip in between.

It would be great being able to bind COM1 / COM2 frequencies to a streaming source like VLC player or the streaming source itself. This way live traffic and live ATC would be available without having to manually mute / unmute VLC players.
