From the video, the chats don't seem to be connected to any Coin - there's no mention of transaction fees to send or receive messages, and they seem to send and arrive nearly instantaneously - more like a Hangouts message than a Bitcoin payment. The app stores your private key too, so this chat service could be using standard public/private key encryption, and a chat server that uses public keys as usernames. Like a PGP chat server - that's in the same app as a Coin payment system, so you can have your private chats and your surreptitious payments in the same central location.
