1. A computer-implemented method for publishing and discovering presence information on a network, comprising:

  • while a local user is on the network, a presence service periodically publishing a contact of the local user representing that the local user is on the network;

    wherein the published contact of the local user includes a lifetime property that indicates a predetermined period of time of how long the published contact of the local user is valid for indicating the local user is currently on the network and a display name and a unique identifier of the local user;

    wherein the lifetime property is provided in case the presence service terminates before an ending message is published in response to the local user disabling the presence service;

    wherein expiration of the lifetime property notified other users that the local user'"'"'s presence on the network has timed out;

    wherein periodically publishing the contact of the local user comprises publishing the contact of the local user with a new display name when the display name for the local user changes while keeping the unique identifier for the local user;

    monitoring for presence of a nearby contact representing a nearby user on the network while the local user is on the network;

    wherein monitoring for the presence of a contact representing a nearby user includes determining whether a user is within a proximity to the local user, and considering the user as a nearby user when the user is within the proximity;

    retrieving an alive message from the nearby contact that includes information about the nearby contact;

    determining whether the nearby contact is associated with an entry within a personal contacts folder of the local user;

    when the nearby contact is not associated with an entry within the personal contacts folder of the local user;

    instantiating a person object associated with the nearby contact;

    populating the person object with the information retrieved from the alive message;

    associating the person object with a contact entry in a people near me (PNM) folder;

    when the nearby contact is associated with an entry within the personal contacts folder of the local user;

    creating a relationship between an entry in the personal contacts folder of the local user and the nearby contact by associating the contact entry in the personal contacts folder with a contact entry in the PNM folder such that when the entry is opened within the personal contacts folder the current presence information of the entry is displayed; and

    producing an output notifying the local user of the presence of all of the nearby users currently on the network.
