Systems and methods for enhancing the exchange of data, particularly media data, among remote locations. In one embodiment, instructions are added to a delivered media message. The instructions are such as to control the processing of the media at the receiving device as well as controlling response messages. This then allows a sending device to enable a return connection from the target location thereby facilitating the return to the sending device of data. The retuned data can be specified by the sender, by the target or by a combination of them. In one embodiment, a intermediary server is used to control the data flow across the network.
