Sounds like a plan.
Oh, by the way, did you want to revisit that fastboot oem off-mode-charge 0 stuff that I mentioned on Google+? I haven't played with it in a long, long while, but I believe that should configure your tablet so that it will automatically boot when external power is applied to it.
That would probably be a great "backup" option for if airplane mode, etc isn't enough to keep the tablet alive for a week or more... so even if it does power all the way off, it won't require user intervention to turn it back on.
