Good evening,

I think that this could be simplified with a strictly Javascript or Ajax approach without using an iFrame.

But, I would agree that some AT users will find it confusing that clicking on a link doesn't actually take them to a new page. I would also say that a JS approach is likey not to be indexed by search engines.
