Pretty cool, I will check this out. I use both Kodi Media Center and Amazon Fire TV to play music via my home stereo. Would really like to be able to play music on that stereo via the Echo is a relatively simple manner.
It shouldn't be too hard. The Kodi API is certainly strong enough to let you make it play music. Something like, "Alexa tell Kodi to play songs by Love And Rockets" would be very easy to add to my existing code.
Cool. I've made a few Alexa Skills now using Lambda. It's very easy to use... would be interesting to see if one could get the integration to work that way. To do so, I'm thinking that mainly I'd need to expose the Kodi JSON-RPC via a public ip or port, and Kodi would have to accept https requests, not just http (probably not supported). And, of course, without any authentication this would the definition of "insecure", allowing anyone on the web who knows the address to control the Kodi :) .
