I went down a similar path on thedailytube.com for sending email forwards. The challenge you are seeing here is with the Environment. The form is checking in setupRender for an existing FormSupport object and complaining because it already exists. The environment that you are trying to render with is the same one you are using to process the form. There are a couple of objects that you will run into problems with (can't remember off the top of my head, and I did it with a much older version). You can try popping/pushing the objects out of the environment while you are running your rendering, but this solution is messy and brittle.
I eventually gave up and just created a separate page with the content and do an HTTP request to grab the rendered content... Good Luck!
