This is a little different than ``security by obscurity''.   Security
by obscurity means that there is a security hole, but you're not
telling anybody about it, and hoping they don't figure it out.

What is being discussed here is not a security hole, but rather a way
to conceal information so as to make an attempt to crack the existing
and hopefully functional security system more expensive.   So I think
this _is_ worth discussing on tech-security.
