    Hi Adam,
    
        I don't know why you are making this so complicated?
        We do not need to review the NuTeV analysis to make a real
    contribution.  I'm suggesting we take advantage of having the world's
    experts on nuclear effects in neutrino interactions, gathered in one
    place, to address a question of nuclear effects in neutrino interactions!
        I also believe that there is a difference in the nuclear effects
    between NC and CC and I'd like to take advantage of the assembled
    expertise to see if we might better understand the physics and, perhaps,
    the size of the difference.  Sharing this accumulated wisdom with NuTeV
    for inclusion in their analysis (if, as I suspect, they have not
    considered detailed nuclear corrections) or comparison with what they have
    done can only help the community understand their result.
        This is just another opinion...
    							Jorge
