    Erik,

 

    I hadn't actually given it a thought until recently, when another friend brought up the idea.  Something along the lines of that reset button on the sub in the movie "The Abyss"?  Push a button every ten minutes or so to reset a timer, or else voltage is applied to some electric solenoid valves to blow the MBT's and surface.  Might not be a bad idea at all.
