The only issue I had with it, which was confusing at first, is the "instances are registered after they've been created by the container" point. If you have a class that's marked with an IListener interface but isn't resolved through constructor injection, that listener will never receive a message. This is obvious in hindsight (never instantiated, so never registered), but it was confusing initially. For classes that aren't resolved automatically, then combining it with IStartable works a treat. This is my personal favourite implementation of an event aggregator.
