Well until it gets added, if it gets added, you could get creative with links using something like the free google hosted sites and some javascript to actually count the number of people that click on a link and then have it redirect back to this page so that by simply clicking on a link it would activate a poll. Once they click on the link and get redirected the javascript on the original site could modify an image slightly and then you could use that image on your blog creating a dynamic poll system... but it would be a lot of javascript and difficult... But its just a thought

I believe there are even javascript php wrappers that allow you to use php functions so that if someone from a specific IP address has already voted it would remove their previous vote and vote into the new category....
