Error handling in a request/response model with the mediator pattern

The mediator pattern Addy Osmani has a great blog post introducing the mediator pattern in his post Patterns For Large-Scale JavaScript Application Architecture. I’ve recently started working with this pattern, using the mediator.js implementation available via npm. Overall the pattern works well when notifying one module of changes in another; for example when publishing state changes. However one area where the pattern seems to fall short is when one module wants to request information from another.
