title: Websocket server for Python3 outside HTTP server
body: <p>I am searching for a websocket server implementation for <strong>Python3</strong>.
  There are some projects on the web, but they all run in HTTP-context.
  I need a server that is started on command line, not by an HTTP-server (No HTTP-Handler object available)</p>
  
  <p>Ideally, the code should not require any bigger third party-project (like twisted, tornado ...)</p>
  
  <p>Any ideas?</p>
  
  <p>Concrete description of my use case: <em>My network contains several python servers (not web servers). Every of these Python servers logs runtime information to a logger. Now, I want be able to listen to those logs from within a browser... and websocket seems the most interesting solution to me...</em></p>
