Looks great!! My 2 cents. Please consider changing link to monitor (or support it as an option) to avoid gen_event mistakes. What if we don't want our process to die when registry crashes. We would have to trap_exits and handle EXIT but how we would know a pid of registry partition in our process to match on. with monitors the process can pass a callback MFA to be called when either registry or the process itself dies. Something similar to gen_server's terminate.
