Just a quick brain dump which may be useful to someone searching for the same thing I was. Enjoy.

function getStylesheet(url, callback) {
   jQuery.get(url, function(data, status) {
        if(status == "success") {
            jQuery("head").append(
                    "<style type=\"text/css\">" +
                    data + "</style>");
        }
        callback(data, status);
    });
};
