1. A method in a server computing device for supporting the communication of presence information among computing devices of a network, the network including the server computing device and a plurality of client computing devices of a user, the method comprising:

  • receiving, at the server computing device from a first client computing device of the user, a request to register the first client computing device to function as a presence agent for the user, the first client computing device being one of a plurality of client computing devices of the user, the first client computing device functions as a presence agent of the user by receiving subscription messages from watchers and transmitting presence documents to the watchers, the presence documents having information regarding the presence of the user on the network;

    determining if there is a second client computing device of the user already registered to function as a presence agent for the user; and

    based on the determining step, revoking the registration of the already-registered second client computing device,wherein upon registration, the first client computing device functions as the presence agent of the user, rather than the server computing device or any other client computing device functioning as the presence agent of the user.
