Hmm... If you're willing to run the scheduler and/or something sending artificial traffic yourself (and are willing to pay for a few warm instances), then it seems like you might be willing to get something very low-latency with these Fly Machines. You could maintain a pool of a few booted and ready to go (but idle, waiting for a request to come in) at all times. When a request comes in you pass that off to an already-warm machine and boot a new one ready for a later request.

Though I think ultimately it's going to be impossible to have all 3 of:

- Ability to deal with large traffic spikes

- Low-latency

- No provisioned resources
