The new credit system should not require the VMs to send callbacks (this makes things easy to hack the system, as we have seen with our Chinese friend). But once there will be a single place to control all VM creations/deletions it should be easy to run a periodic task there to check whether VMs are in a healthy state + decrement credits according to each user’s resource usage.
