@RJ: The code running on my AWS account will only take requests from my official app. I did that mainly to follow the pattern that Amazon suggested in via the templates. But the code is all open (MIT) and there's nothing stopping anyone from running a copy for themselves or others! I could open up my Lambda function so that it can be run by other devs who set up an identical Alexa App. I'm new to this scene - is that something devs are generally doing, or are we mostly just looking at what others are doing and waiting for the official App Store?
