When I say "in the application", it means, in the process of the application.
This doesn't necessarily mean duplicating code, one can use the functions in
the libraries - as we do currently for everything else that happens "in the app"
like the password-dialog and the kio_uiserver's message boxes.

Yes, what you're missing is an extension to SlaveBase::messageBox
that lets the slave pop up a message box (in kio_uiserver's process, via
the application) that contains a lineedit. The current message boxes
are simple yes/no/cancel and such. Feel free to post a patch that extends
the functionality of SlaveBase::messageBox (or adds a new method like
SlaveBase::getInputText), with the necessary forwards to kio_uiserver
and the actual implementation in kio_uiserver.
