My official reply is "Hmm, I don't think you can". I think you'd want to use something like IMouseController and IKeyboardController for the items in the style. IBeadController, if present, is automatically detected and loaded as the controller for the strand (same for the IBeadView and IBeadModel). But you can write your view to load your own classes.
