Modules are, depending on how you implement them, AddOns in their own right (though only useful if you have the main AddOn loaded) so they would, of course, have their own set of SavedVariables. You can (of course) inject those settings into the main AddOn, but at that point there would be no default values (from the perspective of the main AddOn).

EDIT: I was responding to what Myrrodin was saying on the subject. No damn clue how I got so far behind. Yay.
