Looks interesting, especially since it is a protocol on top of another and would not need any additional hardware.
So in theory Almond+ could use this, it is also licensed under RAND-RF so should be at no cost for Securifi to join in on this.
However there is very little information so far, and it is yet another standard, and with both Apple and Google getting into the game, I suppose Google might go for this concidering Nest is part in it. Well we will see. Depending on the complexity it might even be possible for one of the more skilled developers to use the SDK to use it.
This in combination with openHAB could make for a powerful platform.
