snapengage async jquery plugin

jquery.snapengage.js

;// http://www.snapengage.com/docs/asyncload.jsp

// usage: $.snapengage()
// loads snapengage asynchronously. A click on any link with class 'snapengage'
// will cause the chat to open.

!function($, window, undefined) {
  var widgetid = 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX';

  $.snapengage = function() {
    var protocol = window.location.protocol
      , base = /^https/.test(protocol) ? "https://snapabug.appspot.com" : "http://www.snapengage.com";

    $(document.body).append('<div id="SnapABug_W"></div><div id="SnapABug_WP"></div><div id="SnapABug_Applet"></div>');

    $.getScript(base + "/snapabug.js", function() {
      SnapABug.initAsync(widgetid);

      $('a.snapengage').live('click', function(e) {
        e.preventDefault();
        SnapABug.startLink();
      });
    });
  };
}(jQuery, window);

Just a quick note, seems like it isn't that known, but instead of asking for the protocol to determine HTTPS or not you can simply set base to be '//snapabug.appspot.com'. Yup, all I did is dropeed the 'http:' from the URL. This tells the browser to use the current protocol. Too easy :)
