Provide a Zemanta page to prep text for copy-and-paste

This looks like a fantastic tool. Unfortunately, it does not support my blogging platform of choice, Posterous. For those of us who use unsupported platforms or email sites, it would be great if there were a page (kind of like your Demo page actually) where I could write my content, enhance it with built-in Zemanta, and then copy-and-paste it to my email or blog. I suppose I could use your Demo page for that, but perhaps you could provide a page for that purpose?
