My sketchy understanding is that Lua might be able to be called (maybe not now, but soon) by JavaScript (instead of C or C++) via the open source Native Client (NaCl) SDK. So it would be an HTML/CSS/JavaScript/Lua stack - all running within a Chrome browser. Is this possible today, or what are the plans for this?
The advantage would be that in addition to a single version of a Corona/Lua app running on Android, Kindle Fire, NOOK, and iOS, it could also run within a Chrome browser on Windows, Mac, Linux, and Chrome OS.
