Abstract: System and method to enable access restriction to a recorded electronic conversation among a plurality of users, the method including: establishing an electronic conversation among at least a first subset of the plurality of users, the first subset comprising an initial membership of the electronic conversation; recording in a conversation history a change in membership of the electronic conversation; transmitting a notification to at least a portion of a current membership of the electronic conversation; associating the notification with membership of the electronic conversation existent at the time the notification is transmitted; recording the notification in the conversation history; relaying a message to at least a portion of a current membership of the electronic conversation; associating the message with membership of the electronic conversation existent at the time the message is relayed; and recording the message in the conversation history.

Abstract: A computer-implemented method for handling a microflow includes receiving a workflow request that includes a task associated with the workflow and a contact address associated with the task, performing an operation associated with receiving the workflow request that includes at least one of opening a communication session with the contact address and sending a response to the workflow request to the contact address. The method further includes storing the task, prioritizing the task, and performing an operation associated with execution of the workflow including at least one of opening a communications session with the contact address, sending a status associated with performance of the task, and sending a completion status of the task.

Abstract: A mobile ad hoc network is formed by selecting at least one client to function as a Virtual Mobile Server (“VMS”) on behalf of other clients: Those other clients subsequently communicate with a cell station via the VMS on an UWB format. Other clients may function as Virtual Distributed Mobile Servers (“VDMSs”) which relay communications between the VMS and clients which are out of direct communication range of the VMS. Further, multiple VMSs may be implemented for a single ad hoc network in order to bundle bandwidth. Clients may also extend the communication range of the VMS to a new cell station in order to enable earlier initiation of cell station handoff.
