Well, I believe there is a serial only M1 driver for HAL, so you should be able to access M1 functions from HAL. So you could do TTS or other stuff that the Elk either can't or doesn't do well. Since HAL doesn't have an interface designer like CQC or ML you can't really build touch screen interfaces in HAL to interface with the M1. You should be able to get the same functionality as you would with a Homeseer-Elk or AnythingWithADriver-Elk system. You should be able to take advantage of HAL's VR and use it to do things in the Elk like arm and disarm, etc. Well, you probably don't want to disarm by voice, but you get the idea.
