I agree with Sven's analysis and i add that, leaving out performance and 
resources consumption considerations, Gtk-DFB is a valid option only in 
the case a single/few applications are meant to be run on the considered 
device (tat was actually the case of the graphical debian installer).
Otherwise, if many Gtk applications are meant to be run in a 
desktop-like scenario, the best option is still Gtk/X11 + Xserver or 
XDFB rather than Gtk/DFB + DFB due to fact that at GTK/DFB is not yet as 
mature as GTK/X11 in terms of implemented functionalities.
