I guess it is kind of the same thought I have about bicycle locks, in that they
are more of a "please do not steal" sign rather than a real deterrent to theft

Hail is entirely correct, that the only way to thoroughly enforce something like
that would be to encrypt everything... and that is not going to happen, however
a little bit of discouragement (such as http://rb.freedroid.org/r/1603/ ) I
think is worthwhile.

Coupled with lua, it can get rid of the "or did I cheat?" thing in the master arena.
