Abstract
The present invention provides a presence system capable of monitoring state information derived from a plurality of sources over any number of disparate networks. The state information bears on the presence or availability of the user and may take many forms. Based on a profile provided by the user, the presence system evaluates the state information from one or more sources to create presence information to deliver to subscribers. The profile can define different categories of subscribers for which different presence information is provided. Based on available state information, the presence system can provide different views of presence for different subscribers to allow the user to control delivery and use of presence information. Accordingly, different subscribers may receive different presence information based on the same state information.
