[AS3, AIR] Load External Class from content in another sandbox.

Question

The problem is: I have (for example) font embeder class, and I want to load external SWF not from application storage folder, but another local path ( "D:\blah-blah\123.swf") in AIR, but as you understand I can't find any decision on the Internet (Google, Adode.com)

Security.allowDomain() not working in AIR ( documented on adobe.com)


Trick with ApplicationDomain is not working ( same documented on adobe.com)

The all I want, is to get CLASS REFERENCE from loaded content and use in load initiator.

Does anybody knows how to solve this problem?

listing code for getting acquaint:

[main AIR-app code sheet]

// function and one param (path to content)
function tralala( _swfPath : String)
{
    var l : Loader = new Loader();

        l.contentLoaderInfo.
        addEventListener( Event.COMPLETE,
                          function( _e : Event)
                          {
                              var tmp = _e.target.content;

                              // call function from SWF and retrieving
                              // classes, but can't work with them
                              Font.registerFont( tmp._getRef()[0]);


                              // no error checking for clarity
                          }
                        );

        l.load( new URLRequest( _swfPath));
}

function _getRef() : Array
{
    // class1,2,3 are font classes imported in library
    return [ class1, class2, class3];
