I don't do +rep's often, but you deserve it for this.
I've been wanting to do something with io.popen for a long time but nobody on the net can ever seem to give a decent explanation of how the fuck to actually use it, but seeing this, this makes me happy.

Edit: As a side note, the Duties module includes some public helpers that you can utilize if you want to get more specific with the notifications.

NotQueued() - not queued at all
InQueue() - waiting for pop
IsConfirming() - waiting to be confirmed
IsReadying() - readying up
InInstance() - obvious answer is obvious
