Use 'Data Feeds' with products that are priced via configurable options, e.g. SSL Certs?

I've seen that this has been asked a couple of times on these forums, but there's not been an answer (that I can see) thus far.

I'm trying to use the Data Feeds to dynamically display the price of some SSL products on an external page.

But couldn't find any information as to whether or not this is possible.?

Does anyone have any idea on how this could be done, or if it's possible?

Had a closer look and...

I've seen that in the

/feeds/productinfo.php

file there's a line:

if ($get=="configoption") widgetoutput($data['configoption']. (int) $configoptionnum);

So I tried the following:

<script language="javascript" src="https://example.com/feeds/productsinfo.php?pid=1&get=configoption"></script>

and

<script language="javascript" src="https://example.com/feeds/productsinfo.php?pid=1&get=configoption&configoptionnum='some integer'"></script>

But all this gives me is the value '0'.

On viewing the WHMCS database, I'm not sure where this value comes from.

Again, any suggestions appreciated.
