Sounds similar to the service system implemented in InterJinn. I implemented a lookup system allowing retrieval of service objects by custom names. This allows the mapping to be overriden with userland re-definitions which may or may not extend the original class. In this way, a developer can replace components and services without the need to change the code that makes use of such objects. The only caveat is that the override must at least support the methods and properties for the service or component being overriden. I have used this in many projects to extend the core components in InterJinn to provide customers with tailored functionality for their own specific needs. A simple example was overriding the mail service to dupe outgoing emails and store in an archive. It was as simple as extending the JinnMail class, overriding the send() method, and overriding the service registration. And voila, all existing code across the project automatically inherited the functionality, and the distribution code didn't need to be touched.
