I usually export my models from Prefab to AS classes. Then you can include them in swf or swc and just use:
myModel:MyModelClass = new MyModelClass(); I normally also tweak the classes and expose the applyMaterial() method in the AS export. Like this I can load my bitmap materials using something like BulkLoader and then apply them to the "naked" geometry. It's also super easy to add interactivity to parts of a model once it's in AS format. Prefab FTW! ath Jerome.
