從自由軟體鑄造場得知Microsoft 打開 Messenger 大門 開始支援 XMPP，因此目前主流即時訊息都支援XMPP，包括Facebook chat。
既然如此，當然找看看熟悉的Smack套件是否也有MSN的sample code。果然Github上有MS放出的LiveSDK，便有JAVA跟Android的程式碼。有空再把拿token那程式改成用httpclient。
JAVA程式碼如下：
package messenger;
import java.net.URL;
import java.net.URLDecoder;
import javax.swing.JOptionPane;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.PacketListener;

import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.filter.MessageTypeFilter;
import org.jivesoftware.smack.filter.PacketFilter;
import org.jivesoftware.smack.filter.PacketTypeFilter;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.packet.Packet;
