Abstract: In an ECMAScript (JavaScript) Virtual Machine, applications are isolated from the operating system by defining an application context for each application. A root application context is defined that binds scripted objects of the root application context to equivalent native objects of the virtual machine. Other application contexts may send events on an event bus via the root application context to request resources of the operating system. The root application context determines the security privileges of the application context with respect to the requested resource, and is the only application context that is able to interact with the operating system.

Abstract: A method of monetizing a software application for mobile devices. The initial step is developing a software application designed to operate on a mobile device, which is followed by determining a transaction unit for the application. The program proceeds by estimating the bandwidth usage of the application, determining a pricing model for the application and deploying the application, based on the pricing model. Finally, the program performs the step of monitoring consumer usage of the application and adjusting the pricing model as required.
