Add an is being watched flag to RemoteIssue and RSS feed

Would it be possible to add a boolean field isWatched to RemoteIssue and to the RSS feed returned from the navigator?

For jira-dashboard i would like to add a watched decorator to issues that are being watched. This flag would also allow me to add a watch/unwatch action. Currently I have no way of knowing if an issue is already being watched by the user, so the action can't be context sensitive.
