Right. This was indeed a big problem. I like your picture of the system
which is managed by humans is managing the machines available.
Probably it is easy to address this problem automatically, as long as
you have access to all the available resources (machines).
It might get a little more complicated if you manage only a part of the
available resources for yourself, other users managing their own machines.
In this case, you could provide information what attacks to try next,
keep control about who is trying which task, reschedule a task if the
results of that task don't get returned to you after a certain time, and
so on.
Much of this could be done automatically.
