  • a) a data request reception circuit for allowing a first participant system to receive a request to re-prioritize an entry in a transfer queue of the first participant system;

    b) a queue placement circuit for allowing the first participant system to place the request for the teleconference object data in the transfer queue;

    c) a reprioritization circuit for allowing the first participant system to rearrange the request for the teleconference object data in the transfer queue with respect to other requests for other teleconference object data in the transfer queue if an asynchronous request for reprioritization of the request for the teleconference object data in the transfer queue is received by the first participant system, and the teleconference object data has already been partially transferred to a second participant system in the electronic conference;

    d) a transmission circuit for allowing the first participant system to transfer the teleconference object data to the second participant system according to a priority of the request in the transfer queue; and

    e) a queue deletion circuit for allowing the first participant system to remove the request for the teleconference object data from the transfer queue upon completion of the step of transferring the teleconference object data.
