Interaction between two separate distributed applications
Example : We launch from machine A a application 'Get' that launches a deamon on machine B, then runs a module Get and a route waiting for a message. We launch from machine A a application 'Put' that launches a deamon on machine C, then runs a module Put and a route to machine B that sends a message. Result: The message is well sent (here done with a tictac so the return also works)
