It doesn’t matter how easy or difficult it is, if it’s POSSIBLE for someone to talk a user through the steps, including having them ignore all the warnings as they currently do on other less secure platforms (“The man said he was from Apple, so I figured he knew what I should do!”), they’ll do it. Currently on iOS, you’d have to talk them into buying a Mac, then installing Xcode, then downloading the code, compiling it, then connecting it to their iPhone and installing it. AND, I think, calling them back in 7 days and have them re-install the app. Which is a LOT harder than talking them through ignoring a few warnings.
