As an IT department, you install and run your application entirely over a corporate intranet. You or your end users might perform tasks similar to the following:
Identifying the application — You search the Web to identify an application to deploy via WebClient.
Evaluating the application — Your end users sample the application through a live demonstration, installed and executed directly on their systems over the Internet.
Purchasing the application — You buy the application.
Deploying the application — You deploy the application on a local machine.
Downloading, installing, and launching the application — Your end users access the local machine to download, install, run, and update the application, as in the ASP model.
