I don't care about the Best Answer (okay, just a little bit) but want to show it can be done straightforwardly. When we use auto-submit forms we make sure the form is prefixed with "Hidden", "Silent", "AutoUpdate", etc. to set it apart. With the Munchkin call, that's also cool, but it means another Munchkin Viewed Web Page or Clicked Link activity as well (for a page that was already logged at Munchkin.init()).
