following stevenjb, move this to the bottom.

+  static void NullCallback(const std::string& result);

I think you don't need NullCallback or ErrorCallback anymore.

+  static void ErrorCallback(const std::string& error_name,
+                            const std::string& error);
+
+  static void (*on_connected_cb_)(const net::IPEndPoint& ip_endpoint);

could you typedef and document both of the signatures?

+  static void (*on_disconnected_cb_)();
