The only thing that is going to be a bitch about it (besides the fact that its a Beamer lol) are the window mods. If you already have push-button start then its cake (kinda). They are right about the clutch bypass though, I was really carefull with mine and my phone bumped my keys and my car ended up in somebody's yard lol. I think compustar makes one that will not start when it is in gear. Try Area 41 in kennesaw they do some pretty crazy stuff. I would do it but I hate working on German cars.
