Add new category to entire site

Yes, exploding the URI would work beautifully.

Both sub domains would point to the same Web site, the subdomain would simply be used by CI to figure out how to render the site (I used this method on a multi-language site I worked on). You'd just need to figure out the default for how your site will render if neither subdomain are used.
