I would find it useful to be able to display RSS/XML feeds in the default workspace. Here’s why: While supporting a department on a large University campus, we are sometimes affected by information services problems at the university level.
For instance, our users must authenticate against a single sign on (university level) to gain access to our wireless network. Yesterday, the university was having issues with the SSO authentication. They post such problems at http://problem.tamu.edu (the feed is http://problem.tamu.edu/rss.php?area=problem&when=all). Having that feed displayed for our techs would alert them to the issues at the university level, making it easier to troubleshoot and saving them time.
Bottom line: it would be useful to integrate information about services that we rely on, and made available to us, into helpspot.
I would think that others may have a use for this as well. Perhaps the ability to display a feed, or even just an alert and a link when a feed is active, would be a good feature request.
