Abstract: A distribution system and method. The distribution system comprises a computing apparatus and a plurality of projection systems connected to the computing apparatus. The computing apparatus comprises a scheduler software tool and a plurality of audio/video data files stored on a computer readable medium. Each projection system of the plurality of projection systems comprises a cache storage device connected to an associated projection apparatus. Each cache storage device is adapted to dynamically receive and store an associated audio/video data file from the plurality of audio/video data files for transmission to each associated projection apparatus according to a schedule generated by the scheduler software tool.

Abstract: A method, computer program product, and a data processing system for providing pervasive computing with a removable non-volatile memory device is provided. A portable operating system receives a command for removal of a portable memory device from a first host. A running application that is stored on the portable memory device is identified. Application state data of the application is saved in a data structure stored on the portable memory device. The portable memory device may then be removed from the first host and connected with a second host. A determination is made of whether the second host is adapted to run the application. The saved state data is retrieved responsive to determining that the second host is adapted to run the application, and the application is restored to an application state at which the state data was saved.
