I am also interested in your opinion on a suitable mechanism to implement a model focused pub/sub system for simple events.
I am currently using Observers and custom events (ActiveModel::Observing#notify_observers) but the simplicity of this approach and the RegExp matching capability seems to be a better approach to me.
Since I am only interested in my custom events the Observers are pretty much overkill and the presented method would work quite well. Do you see any other major drawbacks than scattering the code (because I need to extract some core business logic into external places)
