Iñaki, you are correct.  Sorry, I was confused looking at my config;  it 
turns out I was thinking of the NAT bflag that comes from the registrar.

What about using add_rr_param() to indicate NAT somehow so that this 
flag can be fished later out of the Record-Route header / Route set on 
sequential requests and replies?
