Cool stuff! I wonder what will be left after the bitter bites of reality for consumer products: consider that we still have actual engineering troubles with things like aluminum in house wiring, which we've been doing for >100 years now.

If you're steering and modulating a beam for power, why not use it for signal at the same time?
