One of our Blog readers Chris P just pointed me to yet another Revit add-in that I did not know about called Xrev Transmit that can be thought of as an eTransmit on steroids. I just checked out their web site and video. It supports Revit 2012 based products and from the little I have seen, I like the user interface, it is clean and consistent. Also love the music loop in the video, it reminds me of Mad Max or Blade Runner
