Tom,

We may be saying the same thing:

if( req->sent_nonce != rsp->rcvd_nonce )
   fail( BADNONCE )
else
   proceed( rsp );

The more interesting question along these lines is the one
regarding Florian's server-unilateral nonces.  I.e. a client
receives a nonce extension in the response even though the
client didn't provide a nonce extension in its request.  While
I'm not yet convinced of this practice's security value, I see
no reason to preclude it in our forthcoming clarification
regarding nonces.
