I can confirm flirc (flirc.tv) works fine with the Shield. Between my Harmony(900) and flirc I have full control over Kodi from my remote. Nvidia only sent certain commands to Logitech in their Harmony profile, buttons like X on the game controller (which will bring up the ContextMenu in Kodi) will not work with the Nvidia Media Remote and cannot be programmed to any Logitech Harmony remote. However, adding flirc to your profile (Media PC --> Flirc --> Kodi) you can assign almost every missing Kodi function to your Harmony. Only issue is it seems sometimes it takes a couple clicks to get something to load from a button mapped to flirc, not sure if it's because it's plugged in to the back of the Shield and it just misses the signal or if it's a compatibility issue with Shield, but it works 90% of the time.
