I am using the "Poll every x seconds for..." to update a status stream and it's working well. However, it only updates with there is a new Heartbeat activity. Is there a way to have it show updates when someone comments or flags a Heartbeat activity?

If there is a way, would it be possible to have that activity move to the top of the stream? Possibly using Radioactivity? http://drupal.org/project/radioactivity

Thanks,
Kevin
