While this workaround has merit, it doesn't actually solve the underlying problem. I guess even Amazon will eventually pick up the phone and ask you to stop sending them weekly bandwidth spikes when the figures involved get large enough (I've personally seen this with another well known PaaS provider).

Why would they?
You'd have to push dozens of GBit/s to even appear on their radar. The only time they'll call you is when they can't charge your CC anymore (a sustained 1 GBit/s will set you back $1000/day at their current rate).
