It's an automotive application, it doesn't need to survive a crash,
simply tolerate non-stop driving for about a week.  So that involves
vibration and water pretty much.

Thought about that but I wonder how easy it would be to remove socketed
ICs and things of that nature.  Not to mention de-soldering something if
need be.
