Well, you're writing the code, I'm in a ltr (not counting btt standing 
stones) area, I was just pointing out how the existing crop bidi apps do 
"handle" (i.e. not do anything clever) the issue.

Maybe one way to handle it would be to make an (emacs level) input 
method autoswitcher, that swaps emacs input methods as the rtl/ltr 
context switches with point movement.  i.e. allow (but don't require)
rtl and ltr contexts to have different emacs input methods.
Then there could be variant emacs input methods with various 
transpositions suitable for use with various os-level keymaps.  And you 
don't have to be able to _record_ whether  an inserted character came 
from the keyboard.
