Sure, it's possible.  useLibrary would parse its argument, 
JS_DefineObject using the name up to the ".js" and defining the new 
object in the global object, and so on.  Beware JSOPTION_VAROBJFIX, 
however -- you don't want this option for this application.

(One way to use JSOPTION_VAROBJFIX would be to temporarily 
JS_SetParent(cx, libobj, NULL) and JS_SetParent(cx, libobj, global) 
around all JS_Evaluate*Script* and JS_Compile* API calls.)
