This was all part of the Lost Experience in the summer, and specifically The Mouth Piece was a code to enter at the Hanso Foundation website. Unfortunately, the HF site has been updated due to "hackers" (part of the ongoing storyline) and since then there is no place to enter the code anymore. Without giving anything else away, if you entered The Mouth Piece in the executive bio for Peter Thompson (or was it for Hugh Macintyre) you got information that made their executive position look a little bit contrived...particularly for the character Thomas Werner Mittleverk, Hanso's second in command and "chief technologist".

Find some of my older posts re: Mittleverk and the HF site, there are more recent clues I've identified if you look for them. They definitely point to what the future will hold for the Losties on the show.
