TVGuardian for Apple TV

Having a feature that would block out profanity, nudity and other moral offensive content from rented or purchased movies in iTunes or any other company offering services through Apple TV would be a very attractive feature to countless families in the United States and English Speaking countries. There is a solution offered by TV Guardian that does this. However, I would really like to see Apple add this as a feature. Anyone that desires to watch clean can do so, those who prefer to watch the unabridged version don't turn the option on. I think its very easy. More $ales too!
