Abstract
A method and system for aggregating presence information generated by multiple devices associated with a single user is presented. A server acting as a presence agent on behalf of a first user and the first user's computing device receives and responds to a subscription request generated by a computing device operated by a second user that wishes to be permitted as a watcher of the first user. If the server is not capable of acting as a presence agent, then the first user's computing device assumes the role of a presence agent.
