DBus is very interesting. I just read the specs. A daemon acts like a messaging 
hub routing messages from one client to the other. If the target application is 
not running it will activate it first. Which may mean actually running the app. 
The messaging daemon can also generate an "event" when a particular service is 
down. Services are defined in a set of config files. Services are just 
associated with executables.  

I intend to use something like dbus to remove the init scripts from my system. 
I will strip init.app down to just the child reaper and launcher for starter 
apps like the messaging daemon itself and login server.
