disabling unlock widgets and some locking questions

[Stéphane Ancelot]

Hi,
I am on the way locking down a desktop configuration, that is from 
javascript creating a defaultPanel .

 From js, when creating default panel , is there a way to inhibit the 
unlock widget menus for applets ?

I have not found the way to inhibit mouse actions from js too .

Is there a way to disable loading of some applets.
eg: in my systray, I do not want the volume applet.
