Debate Plugin/Module for XenForo forum

I run a debate site. Currently, it's just the forum where members debate/discuss a variety of topics. However, I'd like to have a couple more features specifically tailored to debating, similar to: [login to view URL] [login to view URL] <-- probably the better layout between the 3 [login to view URL] Specifically, sort of an editable "tally" for members to give their input and a quick comment about the current progress of the debate. The top of the thread would have the tally score for the Pro and Con sides. Maybe also have a few editable questions like [login to view URL] has. This isn't just a poll feature though. It needs to be able to be changed by the member at any time depending upon how the debate is going. Also, and this could be extra: a way to automate the closing of the debate. Perhaps a visual countdown that is configurable...could be 48 hrs, 1 week, 1 month, etc... See the image for an example forandagainst.com. Doesn't necessarily have to be identical...[login to view URL] is completely different, but it essentially does the same thing: shows which position is currently winning the debate. I realize that XF is fairly new and many freelancers haven't had a chance to check it out. It's similar to vbulletin. In fact, it's created by the original developers of vb. I can grant you access to a dev site so you can take a look.
