Sure, 
But i'm telling dbus-deamon should be that deamon.

Let's say i want to query all the running media player so i can list them to 
eventually play something :  we have to create a special deamon ?
Let's say i want to list all the IM client to know the status of a contact : 
we need a special deamon.
Let's say i want to list all the "kpart" application to know which documents 
are open : we need another deamon ?

I could give many more examples.

This was very possible with dcop.


What i want is  "gives me a list of running services that implement a given 
interface"
