The Desktop Notifications framework provides a standard way of doing passive pop-up notifications on the Linux desktop. These are designed to notify the user of something without interrupting their work with a dialog box that they must close. Passive popups can automatically disappear after a short period of time.
This project consists of a specification (http://www.galago.info/specs/notification/index.php) and a reference implementation (libnotify and notification-daemon).
This port contains the daemon, which will be autostarted from dbus (assuming dbus is running)
See advocacy/84719 (sorry for misfiling that one :/) for libnotify, which is needed for notification-daemon to work.
I'll take this.
