That's facinating! I'd not heard of that in this sense before!
While I know it's meant to be line of sight and/or indoors, I wonder if they would have ways to encrypt the info from these. Not a deal breaker, but I could see the need developing over time.
A lot of improvements would have to be made if we want to use Lifi on a day to day basis .. but still, I think it has a lot of potential!
Oh totally agree, I can see the great potential there. I def wasn't trying to put down the idea, just a curiosity :)
