<p>Publish-subscribe functionality can be integrated into existing instant messaging and presence services (see <cite>RFC 3921</cite>), such that each registered account functions as a virtual pubsub service (sometimes called "pubsub-on-a-JID"). In such deployments, the root pubsub node for each virtual pubsub service has the same address as the bare JID (&BAREJID;) of the account, which is typically associated with an IM user (e.g., <hamlet@denmark.lit>). Since an IM user typically has a roster of "buddies" and shares presence information with those buddies, the virtual pubsub service can use roster and presence information to provide some helpful shortcuts for subscribers, in particular the auto-subscribe and filtered-notifications features described in this section.</p>

<p>Note: Because the account owner's bare JID functions as a virtual pubsub service, it is OPTIONAL for the owner to include a 'to' address when sending publish requests and completing other publisher and owner use cases. That is, when the IM server receives a pubsub-related IQ stanza of type "get" or "set" from one of the account owner's resources, the server MUST consider the stanza to be addressed to the account owner's bare JID even if the IQ stanza does not include a 'to' address.</p>
