Yes, Docky provides a Kiosk Mode:
Docky would be a wonderful addition to an interactive kiosk environment, allowing you to have a beautiful interface to launch the apps your kiosk provides.
In this environment you generally want a read only interface. To achieve this in Docky, you will have to set several GConf values:
gconftool-2 --set --type boolean /apps/docky-2/Docky/Items/DockyItem/ShowSettings false
gconftool-2 --set --type boolean /apps/docky-2/Docky/Items/DockyItem/ShowQuit false
gconftool-2 --set --type boolean /apps/docky-2/Docky/Items/FileApplicationProvider/AllowPinToDock false
gconftool-2 --set --type boolean /apps/docky-2/Docky/Interface/DockDragTracker/ProvidersAcceptDrops false
gconftool-2 --set --type boolean /apps/docky-2/Docky/Interface/DockDragTracker/LockDrags true
Since the Docky icon now does nothing when left clicked, you will also want to either set:
gconftool-2 --set --type boolean /apps/docky-2/Docky/Items/DockyItem/ShowDockyItem false
which entirely hides the Docky icon or set a new action for clicking the Docky icon:
gconftool-2 --set --type boolean /apps/docky-2/Docky/Items/DockyItem/DockyItemCommand "/some/command"
Once these are set, restart Docky. Docky will now disallow dragging (or removing) icons from the dock, have no way to add items to the dock and have no way of accessing the settings dialog!
Please note that some docklets might expose their own settings dialogs/configuration via their popup menus (GMail, Weather, NPR, Clock, etc). Also some docklets will let you modify the system state (NetworkManager, Session, etc). You might want to think hard about each docklet you add to a kiosk environment!
