029/**
030 * (<b>Entry point</b>) An 'in-VM pipe' example which simulates a tennis game
031 * between client and server.
032 * <ol>
033 *   <li>Client connects to server</li>
034 *   <li>At first, client sends {@link TennisBall} with TTL value '10'.</li>
035 *   <li>Received side (either server or client) decreases the TTL value of the
036 *     received ball, and returns it to remote peer.</li>
037 *   <li>Who gets the ball with 0 TTL loses.</li>
