Just another idea to add to the other more concrete suggestions...

If you're happy with javascript being involved, there's a browser 
notification system similar to Growl, you could try, called jsGrowl. 
I've seen it used in the Cobbler web UI where you start a job, then 
later on the notification pops up in the corner of the browser, with a 
link to an 'events log' page. This is independent of the 
queue/job-control. It simply makes a background AJAX request to the 
server every two seconds asking for new 'events', and pops up if there 
is one.
