Yes, I can confirm Lua IDE acceptable by Apple. Did release today without any problems. Had rejection few times, related to outdated screenshots or after uploading transparent icons, but never related to Lua. I think many app games are using Lua or other scripting languages. Theoretically, using script, you can transform your app behavior to anything else, what was not approved by reviewing app store process, only in this case you are loosing trust connection. So if you stay open with your intentions and don’t do harm, you will not have problems with uploading Lua apps to store or you can become suspicious with any person who buying kitchen knife, thinking what he can do with this :) ... and some have really good imagination. :)
