"Android OS addresses this problem with Intents, a facility for late run-time binding between components in the same or different applications. In the Intents system, the client application requests a generic action, e.g. share, and specifies the data to pass to the selected service application. The user is given a list of applications which have registered that they can handle the requested intent. The user-selected application is created in a new context and passed the data sent from the client, the format of which is predefined for each specific intent type." (from Chromium Blog)This is a really cool idea! If you are familiar with Android Intents it will make sense to you. Read the article if not. I wonder whether W3C will embrace this as a 'good idea'. I think they should!
