I agree that a Desktop Environment is a waste.  And--though I'm guessing 
on this--I /think/ that with any of the major Myth distros, you can 
configure them to show the Desktop Manager (i.e. GDM or KDM) on bootup 
rather than automatically logging in, then you can select a Window 
Manager (FluxBox/RatPoison/twm/fcwm...) or Desktop Environment 
(GNOME/KDE/XFCE) for your X session--depending on how you plan to use 
the system during that session.

It's not exactly what you want--but it's not too far from it (and only 
requires logout/login to switch).
