[cap-talk] Communicating conspirators (Re: Second ABAC Google talk is now up)

[John Carlson]

Another experiment might be creating a virus that only
affects one computer.  In the real world, could you create a virus
that only affects one person?   What about twins?

I know that there are things that I do which I cannot get other  
people to do.
Not through lack of trying to explain it, it's just an action that's
hard to explain.

Thus it seems intuitive to me that I could generate some information
that others wouldn't understand, no matter how hard I tried to explain
it.  The question is, is there a way to send information that can't
be retransmitted in a similar fashion?
