It would be cool if we could cast our phone screens to it. That way we wouldn't have to deal with file and app synchronization, cellular tethering, or any of the other friction points of using multiple devices.
That seems to go in the other direction, show Android screen on browser.
Couldn't you cast your Android phone to the Daylight browser? I'm not super familiar with the area, but with the relative openness of Android, there should be other options.
its a good idea, know any good firmware / encoding engineers who could help us build really good casting?
There's a WiFi standard for screen casting. No idea how it works. Support seems spotty, though steadily growing?
