    Subject: For Politech - spam - Draft Protocol for challenge / response 
    systems and Consent
    To: declan@private
    Hi Declan,
    You covered challenge / response systems in the past on PolitechBot. I 
    wanted to point you to a recent Internet draft published by our group that 
    proposes a protocol that allows C/R systems to talk to each other. The 
    original announcement is here:
    We are looking to create a larger "consent exchange" protocol based on this 
    draft, that can allow receivers and senders to exchange their consent for 
    email with any tool, not just C/R systems. This is inline with our charter 
    (http://www.irtf.org/charters/asrg.html), that looks at spam as a "consent" 
    problem. This CRI protocol is one of the building blocks of the overall 
    "consent" system.
