  Lots of cheap sensors and actuators implies designing for unreliable, but
multiply redundant, sets of devices.  eg "Homeowner detected leaving work
at usual time, then detected at end of driveway at expected time, but no
detection of house door being opened.  What's the probability he's
actually home and the house door sensor failed, vs he went to the store
and the end-of-driveway detection was spurious, and what should we do?"
  But the use of Ada is orthogonal to that.
