Abstract: Among other things, techniques and systems are described for facilitating networked communication among media players of various platforms, PCs with various DVD-ROM drives, mobile data processing devices and one or more network servers. At a network server, a request for communication is received from a client device. A secured network connection is provided with the client device. In addition, the received request is processed. Processing the received request includes, when detecting that the received request is a request for data, retrieving or generating the requested data in a platform-neutral format and sending the retrieved or generated data in a format compatible with the client device. Processing the received request includes, when detecting that the received request is a request to send data to another client device, retrieving or generating the requested data in a platform-neutral format and sending the retrieved or generated data in a format compatible with the other client device.
