title: How do I communicate between devices connected to a WiFi Access Point?
body: <p>I have got a couple of phones and another couple of PC's connected to a Wifi access point and need to send and receive messages between either of these, I mean anyone can send a message to anyone and receive a message from anyone.  </p>
  
  <p>I am willing to write apps on the phones(<strong>Symbian OS, S60 platform</strong>) or PC(<strong>Windows</strong>), but what I can't understand is how do I set up a client or server, since any one of these devices could be a client or server.   </p>
  
  <p>If I use sockets do I have to script for <strong>ServerSockets</strong> and also <strong>Sockets</strong> on each of these devices? Can I use the <strong>HTTP protocol</strong>?</p>
  
  <p>Alternatively any standard protocol that I could use to implement this?</p>
