This is, of course, the same strategic policy the US military had when it created the Global Positioning System. In fact, it originally deliberately introduced errors into the unencrypted GPS channels to reduce accuracy. I think this is no longer the case, though.

My father works for one of the contractors which developed GPS in the first place, and I remember thinking it was extremely cool when my dad borrowed a military issue "crypto keyed" receiver for family vacations.

How does it steer?

So, uh, can we get a who's-who from the Happy Mutants so we know who you are ingame? I'm Snagglebert Fistolbars.

Also, don't forget that heating up water for a wet shave takes energy too!
