The write-up was great and had some good details but seems more intended to drive marketing efforts than an actual tech demo that can be verified by users (with beefy devkits a requirement, I'm sure). I didn't see a DIY in their section of papers that have accompanying code yet ("watch this space" I guess?):

I'd be more interested when they can share that.
