ano - do you have some screenshots of the CQC HAI interface? I was looking yesterday but only noticed some basic stuff. Does the CQC interface work with all of the HAI plugged in devices (connectivity partners stuff?).
Well the good/bad thing about CQC is there are no "stock interfaces." So everything must be created. However,
here is the CQC HAI driver page which lists all the commands that CQC uses to communicate with the HAI panel. Looking at it, it seems that it handles alarm, thermostat, lighting, and audio commands as well as allows you to speak messages, make calls, etc with the panel.
Creating the interfaces really isn't hard. Everything is point and click. It can take a little getting use to, but in the end it is infinitely customizable and therefore it is easy to get some very professional looking interfaces with it.
