I want to create a simple online poll application.  I have created a backend in python that handles vote tracking, poll display, results display and admin setup.  However, if I wanted a third party to be able to embed the poll in their website, what would be the recommended way of doing so?  I would love to be able to provide a little javascript to drop into the third parties web page, but I can't use javascript because it would require a cross-domain access.  What approach would provide an easy general solution for third parties?
Make your app into a Google Gadget, Open Social gadget, or other kind of gadgets -- these are all designed to be embeddable into third-party pages with as little fuss as possible.
