Description of problem:
Enhancement: It would be worthwhile to add User Selector Applet, a
gnome applet that allows for fast user switching like in OSX or Win
XP. It works with GDM.
Please file this upstream at gnome.org. If this is implemented
upstream, then a future version of FC will have that feature.
