The one good thing that can still come from this thread, actually there's a few.
The devs will fix the auto-logout so it can't be so easily circumvented.
The devs will decide that 30 minutes is maybe a little short, provide us with an option between 15 and 60 minutes.
The devs will decide that having the tone be adjustable, both what tone is used, and how loud.

At the moment there may be a surplus of space, though I'm inclined to think that is due in large part to the fact that we can't just sit idly 24/7, but population surges tend to happen with patches and expansions. How annoying would it be to be locked out for 3 days after 2.1 hits?
