I wouldn't use one because the signals are coded and you'd have to decode them first before you could use them. I've got other ways to do what I need remotely. By the way, your link in the question doesn't work. What's it supposed to go to?
Because nobody else has needed one yet. Sounds like you do. Post an Instructable when you've made it work.
