Aftermarket alarm/remote start?

Does anyone have an aftermarket alarm and/or remote start installed in their 2006+ A3? If not, has anyone done any research into it? Are there any potential snags to avoid? How difficult is it to bypass the factory immobilizer?

I'm not planning to do this anytime soon, but I'd like to in the future. Plus, I am bored and would like to inspire some discussion. So, discuss!

its been well covered
