Embedding fonts in separate swf files and loading them at run time dynamicly

1

As the header would imply, I want to embed fonts in separate swf files and then load them at run time dynamically. I have heard from the grape vine that this is possible now in AS3. Any one have or know of any documentation on this? I have a project that will use a text field that will have a font style changer for the end user typing the text.
