What we're doing for alarms is having the application provide a URL that gets called if the user clicks on the notification. So the clock app sets up an alarm and sets the URL to "alarms:///foo/whatever" and registers for that URL in the URL Dispatcher. When the user clicks on the notification the Date/Time User Service then sends that URL to URL Dispatcher and closes the notification. URL Dispatcher (and all the app startup machinery) takes care of running the app and then the clock app shows the data to the user. This nicely makes it so that the Date/Time User Service doesn't know much about clock app and can be used for other types of alarms for other applications. This doesn't directly solve the problem for the Download Manager as URLs do require the application to startup and be shown to the user, and for instance in the click case, we'd want that to happen in the background (I assume). But, I'm not sure how 3rd party applications can interact with the Download Manager to get background downloading, perhaps it would work for them. Then we could handle the click scope case as the special case. Ted
