Hi,

Read this:
http://aralbalkan.com/360 (Assimilating _root in FAME)

Although he uses it to "assimilate" _root you can use the same technique 
to "assimilate" any movieclip into an Object.

And any SWFs that are loaded into other SWFs get to run their very own 
main(). The first argument of main() (appears automagically) is the 
"_root" of your SWF.

So in the main class of the SWF Foo have:

<code>
// this is needed for mtasc -strict when setting scope
private var __constructor__:Object;

static function main (scope:Foo) {
	var foo:Foo = new Foo(scope);
}

private function Foo (scope:Foo) {
	// Assimilate the target
	scope.__proto__ = this.__proto__;
	scope.__constructor__ = Foo;
	this = scope;

	// now foo refers to the root timeline of the SWF Foo
}
</code>

You can use "foo._parent" to refer to Container should you need to.
