Well it depends. Maybe yes and the percent could be computed on the
kuiserver, or maybe we could let the progress slot, and let the job
decide what it want to do. For example: If an app created a job that
inherited KJob is copying 1000 contacts and then it has to do
something with them (some heavy calculations), the progress could be
the overall progress (copying + computing), and the message could
change in running time with the infomessage slot, instead of getting
at 100% when finished copying, and then delete the job, so we can make
it more versatile.

Applications don't have to know what the kuiserver does on the
implementation. So I don't think is a good idea an app sending
something like progressDescription("%1 of %1 contacts added");, since
the app shouldn't know that on the kuiserver we are doing something
like i18n(internationalizedText, howMany, howLeft);

As we talked before, probably the Observer will be removed. The
jobuidelegate or kjobuidelegate at kdeui can ask kuiserver.
