Device capability based discovery, packaging and provisioning of content for wireless mobile devices

A network server system includes a download manager that manages the publication, purchase and delivery of digital products from multiple suppliers to wireless services subscribers in multiple domains. Product suppliers can publish and manage their products on the server system via a computer network and make their products available to the subscribers for purchase or licensing. The subscribers in each domain can access the server remotely to purchase rights to download and use the products on associated wireless communication devices. Multiple different implementations of any product can be maintained, where each implementation corresponds to a different set of device capabilities. Each product can also be associated with multiple different provisioning models, each corresponding to a different set of device capabilities.
