they do have alarm that works via sattelite but its 900$ for the system plus monthly fees. It does not however send pages via sattelite. Its just tracks it using sattelite. Also you can log on the internet to your account and track your vechile, say if you let a friend drive it. Also they got some crazy feature where you can remote start/kill it via satelitte on your computer. You can also recieve emails via email everytime the vehicle goes over the speedlimit or goes outside borders you have set that the vehicle cannot go. Sounds to me that its geared towards controlling parents. I was reading a pamplet at CC on it.
