No, don't ship the SDK by default. Make it so that it only runs locally-compiled binaries. That's okay. But I'd like the ability to use this for real work that I do. Everybody else gets to work on it, after all.
Install Parallels Access on your iPad Pro and your desktop compile engine (iMac? Mac Pro? Mac Mini? MacBook?).
