Must admit, a description of localhost tunneling didn't make sense to me since the localhost was more like the endpoint (but not of course when the connection being initiated from the client), but the explanation on the link you shared of Stream Multiplexing made it clearer - neat idea.
FWIW, I personally used to use the solution if NoIP, same result, instead that application was just reporting your current IP to the service.
