The modular expandable units (11-15) send digital information packets from one to another over the exchange (1) in response to requests for these digital information packets. The exchange (1) allows for billing and other administrative functions. A virtual menuing system is disclosed for use with the exchange (1) allowing a simple choice of digital information packets to be published and/or subscribed to.
