I have several library classes that I am loading from swfs external to my main swf.

These swfs all use the native tween class (import not extend).

This means that I have the tween class creating bulk several times over (as well as the extra bulk for having to load a swf rather than having the class internal).

Is there a way that I could make the tween class accessible at runtime to the loaded swfs without having it create the same extra bulk in all of the loaded swfs?

the only solution that I can think of is to create yet another swf with the tween class as a library object, that would be loaded at run time by all the other loaded swfs.

All suggestions welcome.

Thank you for your consideration.
