I'm actually not in the camp which is saying SSH on your phone is a bad idea because the NSA can log into your server. I would actually advocate for using SSH from your phone, instead of this setup. My point is that for all intents and purposes, SSH will work forever. WhatsApp on the other hand, might disappear tomorrow, rendering whatever you built here useless. The crucial point is open vs. closed software and ecosystems. You're putting effort into developing something inside a walled garden which may be shut down tomorrow (or where you get kicked out tomorrow, but the end result is the same). Support libre software! :) /rant EDIT: pedantry
