IOW, users will run Termux under Emacs instead of running Emacs under 
Termux.  (Yes, that's a simplified way of presenting things, but it's the 
idea.)
Concretely speaking, this means that the same programs will be installed 
twice on the same device (which typically do not have a large storage 
capacity): in the /data/data/com.termux directory, and in the 
/data/data/org.gnu.emacs directory.
Concretely speaking, this also means that all programs installed in the 
/data/data/org.gnu.emacs directory need to be built from source, either on 
the Android device itself (but they typically have slow CPUs) or by 
cross-compiling them on a faster computer.
I've also looked at the "exec" subdirectory in the feature branch.  You 
may be aware that the hack you use there to circumvent Android's "write 
xor execute" security policy has been rejected by the Termux developers, 
and that in all likelihood that hole in Android's security policy will be 
patched sooner or later.
