A dynamically configurable presence service provides support for heterogeneous presentities. Presentity types are registered using a presentity manifest that includes information such as type names, addresses of applications associated with actions related to the presentity type, application parameters, icons for watcher application, and the like. Users (watchers) can then register for different groups of presentities based on type and receive updated presence information. Watcher applications are dynamically configured for presentation and management purposes based on updated presentity type information.
