Hi Justin, John, and Hannes

Is there an appetite to change the draft in such a way as: 

- do not wrap access token itself. It could include at_hash though. 
  Rationale: Pop access token can be pretty large and I do not want to
double base64url encode. 
- perhaps change ts to string to accommodate nonce like string. 

Essentially, what I want to do is not the http signing but just the pop
based 
client authentication, which is very simple. 
While I was writing it up, it occurred that if the above modification were
done, your draft will be a superset of what I wanted to do. 

My write up is here: http://bit.ly/oauth-jpop

Financial API uses cases needs something like that. 
(Another possibility is a sender confirmation.) 

Best, 

Nat Sakimura
