1. A method for segmenting a software application into a set of separately executable images, the method comprising: separating the devices to be encountered into classes according to their possible resources and capabilities for carrying out one or more aspects of the intent of the application; separating the environment or operating requirements likely to be encountered into classes according to the needs for distinct rendering or other runtime requirements for carrying out one or more aspects of the intent of the application; specifying the data, code, content and other digitally representable resources needed for an executable image needed to be able to carry out one or more aspects of the intent of the application on each class of device and each environment or operating requirement; generating a utilization plan for choosing which devices and corresponding individually assigned executable images are to be run on each device to be used to carry out the intent of the application given a list of candidate devices, their resources and capabilities, and the required or desired environment or operating parameters; and specifying the data, code, content and other digitally representable resources needed to implement and carry out the utilization plan on each class of device and each environment or operating requirement.
