  Linux-Mobile-IP
            An implementation of Mobile IP for the LINUX operating system
            developed at the State University of New York, Binghamton
            (with partial support from the Center for Computing Technologies).
            Except as noted in the accompanying documentation, this
            implementation complies with revision 16 of the Internet 
            Engineering Task Force (IETF) Mobile-IP draft.
