Even hourly isn't good enough. If I shut down some service, I want to know right now that nothing billable is left over. I don't want to have to wait an hour and come back and check only to find I forgot to clean up some IP address.

Why can we not have a "billable items" dashboard which simply shows, globally, a list of all items in your account which are billable, and how much they will cost if left running for 1 more hour/month?
