Very cool stuff.
Here's a future I'm envisioning for this:
- Built into the OS
- Built with our local-first networking stack (currently an experiment in Aardvark). This will establish a usable UDP connection for you, punch through NAT, etc. Also automatically pairs devices you own
- Copy Apple's trick that uses (ultra)sound + microphones to automatically determine relative positioning of the monitors
This would make it super seamless. On par with Apple
