WoL is reliable when waking from sleep/suspend. I have yet to see consumer HW that can do it from poweroff. But if suspend is fine, all you have to do is configure your firmware to turn on after power loss (so you always boot into your OS) and in your OS enable WoL and configure suspend on inactivity as you wish. It should be reliable and failures would default to "on", not off.
