No it hasn't AFAIK.  It would be nice to have.



"If nature has made any one thing less susceptible than all others of  
exclusive property, it is the action of the thinking power called an  
idea, which an individual may exclusively possess as long as he keeps  
it to himself; but the moment it is divulged, it forces itself into  
the possession of everyone, and the receiver cannot dispossess  
himself of it."
