What's the latency like with that? When a user causes a wake event, how long until the server is live and ready to play? What sort of wait system do you use? This sounds really cool.
In my setup it is instance start + cron job timer + MC server initialization. AWS instance wakes up pretty quickly, cron job is configurable (I set it to 15 seconds or so), MC may depend on the size of the world and any mods I suppose (we played vanilla). All in all took between 40–100 seconds I think.
