> Implement a strategy-based ObjectProvider.  Basically, the provider would choose different
strategy objects (that implement the service interface) based on information obtained at runtime
during the method invocation.  One example would be a strategy-based provider which chose
its strategy object based on the type of object passed in as one of the method parameters
(similar to HiveMind's strategy support).  For example, suppose I have a service interface
like:
> {code}
> public interface Renderer {
>   public void render(Shape shape);
> }
> {code}
> and I want to provide different implementations for Circle, Rectangle, Triangle, etc.,
then I would provide a mapping from those types to implementation objects that also implement
Renderer.  Proxy would create a dynamic proxy that would choose which implementation object
to use at runtime based on the type of shape passed in to the render method.
