[BRLTTY] Would BRLTTY be of use on Android?

[Nolan Darilek]

Where would you hook a wired display into an Android device? None 
supports USB host mode to my knowledge. Maybe some of the newer tablets 
do, but you'd have the same restrictions as you do under IOS with 
bluetooth-only, so you aren't losing anything over any other mobile 
platforms.

Not every blind person has a bluetooth display, but similarly, not every 
blind person has a smartphone. We have to develop for the tech that 
exists, not for the tech we wish did.
