cocos2d-x would not integrate too much open projects to became “a fat platform”. You can use our engine to resolve graphic renderring and sound effects playback, then please integrate other open projects to your game to deal with network and so on.
For sockets you can take a look at Poco: http://pocoproject.org/
There is a module for tcpsockets. Here are some tips for building it for the iPhone: http://pocoproject.org/forum/viewtopic.php?f=14&t=4844
For md5, you can probably also use Poco.
