Casinos offer a unique challenge for communication.  Keeping the guests informed of opportunities, and events, in multiple languages without creating an environment of audio chaos is a challenge at best. 

General information channels in multiple languages could ease the burden on the staff and direct the patrons to the opportunities they seek. 

In recent years high stakes gambling has become an official spectator sport.  Fans wishing to listen in on commentary are a perfect application.  Sports books with multiple screens of video coming from all over the globe can be easily disseminated to separate audio channels for the guests in the salon without any disturbance or noise for the other patrons to deal with. 

Many casinos take on the roll of classroom to insure that the guests get the most out of their experience. There are a myriad of opportunities for teaching when you have the ability to connect directly to the guests.
