You would need each device to have a reachable external ip address.....

Existing methods available should suffice to create a private chat?

Did you try Juan Antonio's example using Ulrich's extension ?

Extension: UDP. Send text. WiFi. Source code

3.- Chat with two mobiles. In each mobile we put the IP and the port of the other mobile ("To IP" and "To Port"), we also establish the port through which we will receive the information. [extension_udp12]
