You can add a rule like this :

rules: {
    6_letters_code: {
       required: true,
       remote: "process.php"
    }
}

where process.php is the PHP URL you want to use to check the CAPTCHA - all you need to do is return true or false.

Details of the remote option here

Your PHP should be something like :

if(empty($_SESSION['6_letters_code'] ) || strcasecmp($_SESSION['6_letters_code'], $_GET['6_letters_code']) != 0) {
   echo "false";
} else {
   echo "true";
}

It seems that the remote option uses get instead of post. There is a live example here you can use Firebug (or any browser debugger) to see the AJAX being sent/received
