How do you access the Ip Address in the Web Player?

So I managed to get it working, but I feel like it was through a dirty hack. I still feel like there should be some inside unity way to get the IP Address and I haven't found it yet. That being said, here is my current solution:

put a crossdomain.xml file on the server hosting the file

 <?xml version="1.0" ?>
     <cross-domain-policy>
     <allow-access-from domain="*.EnterYourOwnDomainHere.com" />
 </cross-domain-policy> 

put a getIp.php file (which gets the IP address and echos it) on the server hosting the file

 <?php
     $ipaddress = '';
             if ($_SERVER['HTTP_CLIENT_IP'])
                 $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
             else if($_SERVER['HTTP_X_FORWARDED_FOR'])
                 $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
             else if($_SERVER['HTTP_X_FORWARDED'])
                 $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
             else if($_SERVER['HTTP_FORWARDED_FOR'])
                 $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
             else if($_SERVER['HTTP_FORWARDED'])
                 $ipaddress = $_SERVER['HTTP_FORWARDED'];
             else if($_SERVER['REMOTE_ADDR'])
                 $ipaddress = $_SERVER['REMOTE_ADDR'];
             else
                 $ipaddress = 'UNKNOWN';
             echo $ipaddress;
 ?>

Then, inside unity I make a string to hold the ip address. Then I had to use this IEnumerator thing to fill it with a WWW object:

 IEnumerator startIPwww() {
         WWW www = new WWW("http://www.EnterYourOwnDomainHere.com/getIP.php");
         yield return www;
         ipAddress = www.text;
     }

Then in the start method of the script where I want to use the IP I placed:

 StartCoroutine_Auto(startIPwww());

I feel like getting the IP address in the web based unity player should not be nearly so complicated for the end users of unity. Does anyone know a smoother way to do this so future searchers can just call a quickie function and get the IP without getting sandbox errors?
