Hmm... I think this was one of the original intentions in splitting 
KIO::Job into KJob: to allow for a curses-based implementation if 
necessary of the messages and user interactions.

But I say this: do not over-complicate the code for a use-case that does 
not exist. If someone can come up with a compelling use-case for 
text-mode ioslaves (I don't mean GUI-less apps, I mean apps running with 
completely outside a graphical display), we should investigate the 
possibility.

There's simply too much in kio that depends on user interaction, like the 
SSL dialogs or even the rename dialogs. If we were to decouple all of 
those into core/gui, the code could conceivably become too complex to be 
maintained. And all for a use-case that I currently don't see.

Remember: we're making a graphical desktop. The fact that our tools can be 
used in non-graphical desktops is a plus, not the main goal.

The solution in KDE 3 now is that if DCOP isn't running, we start the DCOP 
server and kdeinit. In KDE 4, we could detect that klauncher isn't 
running and start it manually.

KDE applications don't start at all if D-Bus isn't available (running or 
auto-startable).
