Of course -- JSClass.getProperty and JSClass.setProperty can mirror 
changes from and to your std::map.  You can set the JSClass.flags bit 
JSCLASS_SHARE_ALL_PROPERTIES to avoid any parallel map being managed by 
SpiderMonkey.  Then for each get or set, the appropriate JSClass hook 
will be called and you can fetch or store using your map.
