Looks great, Ben! I agree with thebiglebrewski that a link to a demo site would be super helpful.

FYI, I built a similar (paid) product for Shopify Themes (http://bootstrapforshopify.com) and I have gotten quite a few queries from folks asking about a similar thing for Wordpress - there are people willing to pay for something like this, for sure, if you're interested in offering a supported version or something of that ilk.

In any case, now I have somewhere to direct folks that ask about a WP Bootstrap framework :).
