To me the difference in a 'square' checkbox or a 'round' radio button is not really significant. I know it can be for some. And I think CC should address this issue, soon. But for now, I'd just use checkboxes to solve your problem.
True, and that is not a bad idea. I think I may do that, use checkboxes. I really don't want to edit the files manually each time it's republished. This group is still adding fields to the form, and I would be manually updating A LOT. :-(
