Many thanks for the tips. However could you tell me if it is scattered
around or there is a special place that talks about that ? If yes could you
point me to it.
The thing is i have been working with books. I'm working with scala
cookbook, scalation in action which both have chapter on it, I recently
bought Akka in action (MEAP), and someone gave me effective AKKA. Although,
i search and it is only, Akka in action which talk about creating a
protocol object which contain those message. However nothing as fancy as
yours with sealed trait and etc...
