title: send messages to a computer off network python
body: <p>I am writing a messaging software based off of the code at this link:</p>

  <p>I love this code and it works well, but it will not let me send messages to computers that are not on my network.  I was wondering if there is a way that I could modify this code, so that I could send a message to a computer anywhere.</p>
  
  <p>Any help or advice would be great.</p>
