Michael,

You may already be aware of this, but Clifford Lynch did some research last year on this topic (or close enough as to be potentially very useful).  Not sure if CNI could provide the data behind the report.

    Hi all,
    
    We're gathering some very informal data on which authentication mechanisms are 
    being used for single sign-on in academic institutions. Your responses will 
    help us determine how best to focus efforts in an ongoing project. Though 
    we're mainly concerned with institutions in the United States, all responses 
    are welcome.
    
    This short survey has just 5 questions and should take only a moment of your 
    time. We'd really appreciate your participation.

    Thank you,
