Yes, but I think my case is very important (eg, being able to use a MAC token as a client credential). I don't understand why Adam can't comprehend my explanation. My best guess is this is some kind of political game on his front to protect the age specification yet I don't understand any motivation for being so close-minded. His reply to my last thread was completely disrespectful and ignorant. Unless I've made him mad or offended him in some way I see no excuse for this behavior.
I'm going to make one more attempt to try to explain this to him over email. After that I recommend a Skype call (hopefully brief) or I will work offline with Eran to see if we can find some solution. Btw, in addition to the use case of using MAC tokens for client credentials, we also have the use case of re-issuing a valid token multiple times to instances of the same client. (eg, the value of ID and secret are constant across multiple transmissions to client instances).
