Exactly.  But other methods that would protect those necessary casual 
contacts to the good-enough level already exist, and won't needlessly 
complicate interactions the way mandatory secret handshakes would.  If 
you mandated secret handshakes, I'd just determine I never had any need 
to talk to you.  I hope you won't be asking me for venture capital.
