    It's the old PAP versus CHAP debate. *YES*, there is reason for the
    realmedia server to store the password in plaintext (although it
    should still obfuscate it to prevent accidental viewing). I always
    like to compare the types of PPP authentication to show this:
    
    Method  Client     Wire       Server
    ------  ---------  ---------  ---------
    PAP     Clear      Clear      Encrypted
    CHAP    Clear      Encrypted  Clear
    
    And I don't think we can do better than that. We can encrypt at only one
    stage of the process. We have to make a tradeoff.
    
    (Not that I'm saying RealMedia uses the CHAP model and encrypts over the
    wire. It probably doesn't, and if that it the case, then it is indeed
    stupid.)
