I don't think the IPP Model is rich enough to support such a GUI display of the
job queue. In some implementations (e.g., with multiple output devices) it's
hard even to determine the order in which the jobs will print, in order to do
the "number-of-intervening-jobs" or to order jobs properly for the Get-Jobs
Response. In Copenhagen, the group apparently thought the queue concept is too
fuzzy even to allow Promote-Job! But I'm not opposed to extending the IPP model
to inclue a Queue class.
