How to loaded external SWF access "local" Stage?

Hi!

I doing a project which I need to load a SWF form another host, into a SWF on my host.
Ex.:
http://myhost.com/loader.swf [SIZE=1][COLOR=Silver]>> loading >>[/COLOR][/SIZE] http://faraway/loaded.swf

But I have problems when it finishes loading, because loaded.swf try to access Stage to watch for it’s dimensions, I get some security error.

“SecurityError: Error #2070: Security sandbox violation: loaded.swf cannot access Stage owned by loader.swf.”

What can I do to solve that?
