But that doesn't prevent people that never see the spec doc from 
reverse-engineering it.  You have no way to control them, except 
patents, trademark, or DMCA.  Anyway, I think all of this is contrary to 
OSI's purpose.  Embrace and extinguish is certainly undesirable, but OSI 
doesn't want a /license/ that prevents it.
