Very interesting idea. I like it especially around here with all the very "special flowers" on the road.
The only concern I have in regard to adding any sort of technical device to my helmets, Senas included, is the concept of having a LiPo/Lion/LifePO4 battery near my brain. I don't know, but I hope, they all have factored this in the design so that if a battery were to vent, the force and heat would be directed away from your head, outwards. For the same reason I'm not a big fan of battery powered heated gear, those packs especially since they're a lot higher capacity than a Sena or ThirdEye.
