RSS syndication can be applied almost anywhere especially where there are incremental changes to data content.
This is not lost on Glen Scales who, as posted on his Exchange Dev Blog, has been working on a script to generate the necessary XML based on updates to the message tracking log. If message tracking is enabled, Exchange will append to a daily log, message information incrementally. There are several applications that can analyze the message tracking logs and produce reports on the content. But Glen's Exchange Message Tracking Logs RSS Feed Script is a good start toward publishing message tracking log information for people, probably management, to subscribe to down to the user level. Perhaps we will soon see management or administrators getting that information as the tracking log is updated throughout the day.
Glen has been busy applying RSS feeds concepts to Exchange administration, including the basics of an RSS Calendar Feed Event Sink and Public Folder RSS Feed Event Sink. Search his blog for more RSS ideas.
