This is a side note. I've thought about setting up an AWS account just to play around with, what is the likelihood of a senior embedded c/c++ programmer really screwing up and end running up several thousand-dollar bill just because he put an innocuous infinite loop somewhere out of ignorance? :) Is there some trigger you can set such that CPU usage/bandwidth usage won't do something that you will never financially recover from since I won't have any knowledgeable devs to look to.
