Hmm, well considering your scenario its not really going to work, unless of course your model objects are created by one (or more) factories and you can place the logic in there. But i guess you would said if that was the case.
Maybe you can let us know what the most generic contact points are within the app. to try and minimise the amount of work you would have to do. e.g. do a lot of your models inherit from the same class? are they created using factories or instantiated explicitly. Thinking about it, you wouldnt have to refactor the model touchpoints themselves, i.e. the places where the models are accessed, only the places where they are instantiated. The proxies themselves can implement the same interface as the model class so any code further down the line can (and should :) be typed using an interface. If every reference to a model object is typed to a class then you would have to replace the class with the proxy and move the real model code to a new class, which is really what i think youre trying to avoid. I feel like im going in circles a bit here :P anyway, i'll keep thinking and if you can let us know more about the architecture to see what are likely candidates for change points that have the minimum of impact on your code then someone may come up with something really clever. after all, its flash and sometimes you can do suprising things in flash :) good luck.
