You could create multiple sessions for the same channel. To do so, in step 3, open another terminal console for the VM and start the echo server a second time, but on a different port:

1. $ java -jar EchoServer.jar -t true -p 2008.
2. Create a channel specifying this port using step 4.
3. Send the request to see the channel. See the request sent at step 5.

The response will this time contain two sessions:

--[cut]--  
            "session": [ 
              { 
                "session-id": "2", 
               "bytes-in": 0, 
                "termination-point": { 
                  "termination-point-id": "2008" 
                }, 
                "session-alarms": 0, 
                "bytes-out": 0 
              }, 
              { 
                "session-id": "1", 
                "bytes-in": 0, 
                "termination-point": { 
                  "termination-point-id": "2007" 
                }, 
                "session-alarms": 0, 
                "bytes-out": 0 
              } 
            ] 
--[cut]--

You can have as many sessions as you wish per channel. This means you can have a number of devices running on the same host and you can connect to each one of them using the same secured channel.
