In order to receive presence from the publishing entity, the subscribing entity must be in the publishing entities roster and subscribed to receive presence notifications. May I enquire what the underlying reason is that the subscribers need to know the presence of the publishers? Is it possible that the subscriber can assume presence based on whether or not geolocation data is being published? I don't believe that there is an open presence concept, meaning, presence without a subscription to the entity. There is pre-approval but I don't know what servers support it and it still requires the subscriber to be in the other entities roster. > /andy
