How can i broadcast a message using Python whenever i make a cell change?

I would like to be able to setup a python script that broadcasts a message whenever i make a change to a certain cell in the spreadsheet. I will setup another application to listen to this message and respond accordingly. Is this possible? Can someone provide me a sample script in LibreOffice calc python that does this? I assume we would need to setup some server/client relationship where LibreOffice is the Server and sends messages over a network socket.
