I'd ask that you lobby Dish to add National Geographic HD when it becomes available. I don't think it has to be wordy, but just something to let the programming department know if you are interested. I used the email link at http://www.dishnetwork.com/content/faq/index.shtml and just said I'd be very interested in receiving National Geographic HD. I received a reply after just a few hours that they would pass the input along.
Thanks,
Doug
