I appreciate your response, but I think you're rather missing the point of what I'm trying to achieve. I don't want clients of the User class to even know there *is* a Lookup::Remote being used by User, much less have to specify Lookup::Remote as a source for discovery.

The problem is how to communicate a high-level configuration value into a has-a class inside another class, not which has-a class to use.
