Dynamic CrossDomain Iframe Issue

Dynamic CrossDomain Iframe Issue

Hey guys, I'm working on a page on my website where I am trying to embed another website in it. I normally don't like using iframes as much but it seemed like the best possible solution.

Here is the link: http://www.wfaworldwide.com/new/node/43

The problem is that the website I am embedding has different heights based on what you click. So I tried to implement(via jQuery and Javascript) a way to resize the iframe based on the the height of the inner frame. However, I kept receiving a permission denied error on calls to document.body. I did a little research and found that it's quite hard to do dynamic iframe height based with crossdomains. I found some fixes but they required that I have access to both pages to implement Javascript. Thing is that the website I am embedding is a website that I don't have access to so I can't put in the proposed Javascript fixes. My question is does anyone know of a way to fix this or of simply a way to mimic an iframe and embed another webpage into mine?

Any help would be very much appreciated.
