Ah yes, I am remembering vague snatches of that Sunday meeting we had in London.
In 3.1 it states you have to use a hash function of equal size to the JWT wrapper's.  Why don't we just specify that the same function must be used?
Why include a timestamp explicitly here when we could use the Date header?
There's no nonce included in anything here, was that an explicit decision?
How is line continuation handled for header values?  This should probably be explicit about that.
Repeated headers...  "Repeated header names are processed separately with no special handling." this wants to be clearer.  Does this mean you repeated a header name in the list?  (which explicitly should not be allowed).  I think this needs to explicitly say "If a header name is specified then all headers with the same name must be processed for that header.".  The next question is ordering, will any frameworks or proxies re-order headers of the same name?  If so then we probably have to produce a sorted list of headers.  
Do we need to handle repeated parameter values explicitly?

 Yes it did, as part of the PoP suite. It's the current stab at an HTTP presentation mechanism for PoP tokens.

That's easy: any headers. That's why the signer specifies which ones. Would be good to have since guidance tough, and examples.

Hi Justin

I see a fair bit of interest toward this work now being shown from my 
colleagues; it would help if the next draft could clarify which HTTP 
headers can be signed given it is difficult to get hold of some of HTTP 
headers typically created by a low level HTTP transport component.

Thanks, Sergey
