Recently there has been news regarding a GameBoy Advance emulator for iOS that can be installed on stock (non-jailbroken, non-developer) devices called GBA4iOS. https://github.com/rileytestut/GBA4iOS
The developer is achieving this by using a new site called MacBuildServer.com - this site aims to be a distribution point for GitHub projects. They will clone the project, compile it, sign it with their enterprise certificate (or you can provide your own), and allow installation OTA.
In order for this to be an option for ScummVM, the GitHub repository would need to cleanly build in Xcode without any post-checkout modification (something that would be nice for people with developer accounts anyways).
I am sure there are gotchas to this plan that I haven't thought of, but I wanted to start a discussion about it anyways.
