What means the user-input element? Actually device can compare the tuple id from the rpid with himself to keep different presence state himself if he subscribe the presence to himself. and in another case, the two devices can make the state synchronized with each other if he subscribe the presence to himself and do not care the tuple id. So,practically,what is reasonable choice to implement by the client?
