Abstract: Functionality is described for collecting data from a presence-based system, such as an instant messaging system. The functionality can extract information from the collected data based on one or more rules. For instance, the functionality can identify presence data and/or message data that includes predetermined key words. The functionality can formulate result information based on the extracted information for presentation to a recipient. Based on these operations, the collected data supports a data-mining operation, as well as the traditional role of facilitating communication among the participants of the presence-based system. The result information can correspond to a report that presents aggregated findings, optionally organized into one or more demographic categories, or the result information can correspond to an advertisement, etc.

Abstract: Exemplary methods, computer-readable storage media, and systems are described for establishing multiple simultaneous connections on an instant messaging program to enhance the user experience. The user receives notifications of request to communicate, an email, or an alert on communication devices. By choosing which communication device to respond on, that particular communication device becomes active, continuing the communication to transmit to and receive from on that communication device. The process also includes mirroring the communication on the other communication devices that are alive (connected) and non-mobile. Furthermore, the other communication devices are kept alive to allow the user to switch from one communication device to another during communication.

Abstract: Content synchronization in a file sharing environment is described. A node in a circle share maintains a version vector that represents that node's knowledge of file synchronization events. Version vector data may be transmitted between nodes of the circle share via a presence service in the form of short notification messages. The version vector data is compared to identify one or more nodes to be synchronized. A resource-aware overlay representing the circle share is computed, and is used to initiate communication to determine which of the available nodes with which to synchronize will provide the most synchronization value to other nodes in the circle share.
