I know that at some point Gene Lebell and Rickson Gracie had a similar thing going with rewarding people with a patch for achieving a certain level of training in their systems directly through them. Kenpowise, Mr. Planas is about the only one I can think of doing that...although Doc Chapel has a similar system where his black blets are different from his teaching certificates. You have to do more to get the certificate to teach from him.
