I would welcome this, as I have struggled to find a secure chat. In the meantime I've been using bitmessage, but it takes 3-5 minutes for a message to be processed (similar protocol to bitcoin). https://bitmessage.org/bitmessage.pdf
Consider trying Tox, http://tox.im/ ... It's open source and actively in development, but already at a usable stage. It's meant to be akin to skype, but open and secure.
