// Add interface
//
// Simple example application which computes the sum of two integers
// if the sequence number of the call (seqnum) matches the expected value;
// otherwise, add() will return 0.
//
// The sequence of seqnum is established by the SecureRandom
// seed during the initial authentication of the RMI connection.
