No, but there are cases where this can be a desired property in someone
building an application. For example an astronomy sensory network that
deliver sensor data over RTP. In that case you are not talking about
human user's endpoints, and you also may have a private network and want
to make monitoring at key points simple. Thus having the sensors being
provided a persistent name is simple and straight forward.
