LuaJIT is very fast, so that would be a big bonus I guess. Downside it that if you really want to make the most of it, you have to write code in a way that allows LuaJIT to do its magic. So my guess is that your end users will probably learn and write "regular Lua” and that the performance benefits of using LuaJIT will be less. (Still faster, but less faster than possible… how much less…. depends…)
