A device, such as an ADSL modem, acts as a proxy for service endpoints in a data network by responding to service endpoint advertisement messages pursuant to Point to Point Protocol (PPP) over Ethernet (PPPoE), where the terminating equipment located at those service endpoints do not support PPPoE services. The device also supports route selection and transparent protocol conversion of network protocols so that a host computer connected to the device can communicate with the service endpoints where the service endpoints do not support the host computers network protocols (e. g. , PPPoE). For example, the device converts PPPoE packets from the host computer to PPP packets and transmits and receives PPP packets with the service endpoint. The invention bridges a huge gap in the existing telecommunications infrastructure. The vast majority of the embedded base of product capable of acting as a service endpoint in the PPPoE protocol (such as the remote access server infrastructure providing dial-up Internet or corporate network access) does not presently support PPPoE protocol, whereas they do support PPP.

Current approaches to paperless books use single screen laptop computers or electronic paper display (EPD)-based book readers. Laptop computers consume too much power and cannot be used for extended periods of time, such as an entire school day, without recharging its battery. EPD devices are limited in functionality due to their slow refresh rate and grey-scale only images. An embodiment of the present invention integrates bi-stable display technology and refresh display technology into a single device and manages the use of these technologies to achieve power savings while providing a rich set of display functionalities to support user interaction with content in a synergistic manner. The power savings functionality enables the device to have a battery operating life between charges of many hours of operation, such as eight hours or more, while the display functionality enables users to access, display, and interact with content in ways users have become accustomed and in ways not before possible.

A method for efficiently setting up a data transmission session over a communication channel between a local endpoint application and a network endpoint application with a proxy engine in a manner that is transparent to the user. The proxy engine is placed in simultaneous communication sessions with the local endpoint application and the network endpoint application. The proxy engine determines the network control protocols that are supported by both the network endpoint application and the local endpoint application. The proxy engine enables the network control protocols that are supported by both the network endpoint application and the local endpoint application. Optionally, the proxy engine enables data compression techniques that are supported by both the network endpoint application and the proxy engine. After the network control protocols and data compression techniques (if desired) are enabled, the proxy engine transmits data between the local endpoint application and the network endpoint application over the communication channel.
