I think that would be using a screwdriver to hammer a nail in with.

One could create a loop around smg$read_keystroke, replace
all smg$read_string call with lots of application code,
open multiple virtual keyboards to multiple terminals
(input device is an argument), use smg$read_keystroke
with a timeout and try multiple virtual keyboards.

It would require lots of code and perform poorly. And
I don't really see the use case.
