Client side security trim DOM node

I know that you can apply security trimming to .aspx pages via the <SharePoint:SecurityTrimmedControl> control, but is there an equivalent way of security trimming dynamically generated DOM nodes - client-side only?

For example, I have a node being created from a function that will be injected into a SP.UI.ModalDialog object.

var modal = function (title) {
  var container = document.createElement("div");
      container.innerHTML = "This is something that should be security trimmed";
      container.className = "button half bg-green";
      container.id = "trim-this-mofo";
  // how do you security trim the node created above?
  var options = {
      allowMaximize: false,
      title: title,
      html: container,
      showClose: true,
      width: 750
  };
  SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options);
};

Again, this is client side only.
