Systems, methods and computer readable memory devices for delivering a presentation are provided. In one example, a method includes communicatively coupling the host computing device to an external router, and establishing the closed wireless network using the router. An encrypted communication session is established via the closed wireless network with a plurality of client computing devices that each comprises a display. Each of the client computing devices is communicatively coupled to a virtual network server on the host computing device. Frame buffer data is retrieved from a storage subsystem of the host computing device. The frame buffer data is sent to each of the client computing devices to modify the display of each device.
