    It's tunneled in a bastardized way through HTTP Auth: requests. You do a sort
    of 3 way handshake. The best reference implementation I've found is in Squid,
    which isn't that nice for what we want though.
    
    This is the best documentation I found on the
    subject: http://www.innovation.ch/java/ntlm.html
