I recently read about a feature in Windows XP that allows you to log in,
run a GUI app, log out and have the app continue running in the
background until the next time you log back in when you can continue
using it.  Does anyone know if there are any plans to do this under
Linux/X11?  Anyone with X11 programming experience suggest how it would
be done?  Something in the window manager, perhaps?
