Getting around SecurityError #2070

So, today I started playing with some SWF loading code in Flash Builder, and I ran into a common sandbox problem.
You get Error #2070 when a loaded swf in another directory tries to access the stage.
I couldn't get around it by using Security.allowDomain("*") either, because it was an AIR application.
So, to get around this problem I decided instead of directly loading the file using Loader.load() I'd load it by loading the file into a byteArray and useing Loader.loadBytes() instead. and guess what? it works.
It completely gets around the sandbox issue.
Have some code:

 private function loadSwfFromUrl(url:String):void{  
      var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);  
      var ldr:Loader = new Loader();  
      var swf:ByteArray = new ByteArray();  
      var fs:FileStream = new FileStream(); File(url), FileMode.READ);  
      context.allowCodeImport = true;  

There's probably a better, simpler way to get around this sandbox issue, but at least this works.
