Abstract: Methods that enable real-time communication and collaboration in a peer-to-peer (P2P) network are provided. More specifically, methods for the creation and access of an underlying graph and/or group structure to pass collaboration/real-time communication data and other functions such as the retrieval of node/member and graph/group information, the addition, modification, deletion and management of records (data), the direct communication between graph/group nodes/members, the registering for event notifications, and other functions are used to pass real-time communication/collaboration data between nodes in a graph or members of a group.

Abstract: An improved information presentation system and method enable the automatic connection of a presenter's device to a projection screen or other projection target. The system and method allow device discovery and session establishment with minimal effort on the part of the presenter. In an embodiment of the invention, a reverse terminal server model is utilized to establish a connection from a presentation server, or projection device, to a presentation client, or projection target. The discovery by the projection device of the projection target is by way of the Universal Plug and Play protocol, whereas exchange of data to be exhibited or manifested is by way of a terminal services session commenced via a reverse terminal server model. With respect to visual materials, shadowing may be used to provide the display on the terminal services server host while the terminal services client host renders the information for presentation.
