Yes, exactly.

No, as this hasn't yet been given much thought. Right now, you need to use
openTtyWithPath(0, NULL).

I'm unaware of Androido providing a way for a user to create a container. A
container, if created, would, of course, run just like any other container.

Input isn't read that way. On Android, brltty provides itself as an input
method. Of course, a second brltty within a containner running Linux would use
/dev/input/ devices.
