A provisioning system provisions a mobile software application to one or more remotely-located mobile computing devices. The remotely-located mobile computing devices may each have a native operating system. The mobile software application may include executable program code and a structured document such that the executable program code and structured document together instantiate at least a portion of the functionality provided by the mobile application. Moreover, in some embodiments, when the requested and sent mobile application is executed by a requesting mobile device, the structured document is parsed into a Document Object Model tree structure which when updated, updates at least in part the running state of the mobile application.
