May not be available in your area, but it is in others.
I also tried to find info on Dish's website, but it wasn't there. I called Dish last Friday about getting this bundled, and moving off a 3G MiFi for our home Internet connection. Installation was scheduled for Monday afternoon, though they arrived around 11:15 after calling ahead. A couple hours later I was surfing at much higher speeds.
15GB a month for basically what I was paying for 10GB before. A 240MB download of a PS3 game add-on, which would have taken a few hours on our 3G connection, took around 4 minutes. Latency is worse, but it's more than made up for with the overall speed.
