Maybe important, the implementation[1] was made using 
draft-ietf-emu-eap-edhoc-00 and since then the channel-binding section was 
added.

Can anyone chip in and state if the channel binding with validation was ever 
implemented anywhere?

The draft states "the channel binding protocol defined in [RFC6677] must be 
transported after keying material" without anything material (to me) on how to 
actually go an do this as an implementer.

For example what is the actual process in doing "If the server detects a 
consistency error in the channel binding information contained in EAD_3" and 
how does a peer respond if it is upset?

Cheers

Alex
