    - unify the queue so we can have a global away without the dialog
    - handle and update tooltips to show your current accounts/queued messages?
    - show a count of queued messages in the unified queue
    - dernyi's account status menu in the right click
    - optional pop up notices when GNOME2's system-tray-applet supports it */
