Design phase 2 of adding communication to demo

[conradoplg]

In the first phase we added simple socket communication to the demo, with the coordinator acting as the server.

Design phase 2, which increments the previous phase somehow. This could involve, for example:

• Decoupling server from coordinator
• Integrating some other third-party library
