Communicating User State During Pending Interaction

[jricher]

§5.2 Continuing During Pending Interaction: Editor's note:

Extensions to this might need to communicate to the client what the current state of the user interaction is. This has been done in similar proprietary protocols, but the details of that information tend to be highly application specific. Like "user hasn't logged in yet", "user has logged in but is still sitting at the page", or "user seems to have wandered off". We might be able to provide a decent framework for hanging this kind of stuff on.
