title: Portable Realtime bidirectional library that doesn't use HTTP procotol
body: <p>Could you suggest a portable library for creating realtime bi-directional sockets that do not rely on the HTTP/S or any other plain text protocol? I'd like to send data up and down in the smallest chunks possible.</p>
  
  <p>The protocol must support TLS</p>
  
  <p>Everything to do with WebSockets is off the list.</p>
  
  <p>Though portable, I'm specifically looking for something that will work in Python and Java (Android)</p>
  
  <p>Thanks.</p>
