WiReboot will check if it can connect to Wi-Fi and if it can do a https post to google hosted server.
In plain English, it will check if it can access a web page hosted on Google. It will also retry n times for every n seconds (default is 5 times, 5 seconds) before power cycle.
You will be able to change all these settings when WiReboot starts shipping.
I am working on over the air firmware upgrade, if it works, more features can be added later.
