Disclosed are a system and method, also referred to herein as an architecture, for efficiently communicating a high volume of data from a server over an electronic communications network to geographically disperse recipients, where one or more of those recipients may receive a customized version of that data, e.g., content, timing and/or form. As the data is generated, timing information and/or changes to information regarding customizations is incorporated forming a data stream which is communicated to local data publishers (“LDP's”). Upon receipt, the LDP's extract the data, customization, or timing information and act accordingly when transmitting the received data to the recipients. Customization is applied to update local control databases which specify the customizations for subsequently received data before transmission. By acting on the messages in real time, e.g., as they are received, the LDP's, even if they don't receive the messages at the same time, then perform the same functions in the same relative order relative to the data stream.
