So if I understand correctly there will be a progress slot (which will 
indicate the percentage) and an info slot (which will contain messages 
such as "Copying 12 / 1000 contacs..." or "Doing heavy calculations...").

What I meant with progressDescription is the same as your info slot.  So 
the kuiserver would only show the string without doing nothing with it.  
It's the application that would do something like this pseudo code:

myJob->progressInfo(i18n("%1 of %2 contacts added", howManyDone, 

Would this make sense?

ok. sounds good!!
but then the kuiserver would have nothing of UI (user interface), no? Is 
kuiserver still a good name? maybe better kjobserver.
