I was looking for a way to turn my android phone into a bluetooth keyboard and mouse, which was unsuccessful without root. However I found InputStick which looks like it would work well enough.
InputStick is a USB device that has bluetooth, which your phone connects to. The device InputStick is connected to thinks that a USB keyboard and mouse have been attached.
Has anyone used this with a Nvidia Shield TV?
Sounds similar to FLIRC which receives IR and simulates keyboard presses. I've been using FLIRC with Kodi and a harmony remote with no issues. I would assume that your device in question would work fine.

Isn't this a broader version of what has just been announced by Comcast and EA with their 'XFINITY Games' service on the X1 box, but functional on unmodified Android and unmodified iOS devices?

This technician didn't have any gaming controllers for us, nor did he point out any USB plugs we might use to attach our own controllers. Xfinity Games has a steeper controller requirement. After having our Xfinity account greenlit for the beta, we loaded the X1 app, at which point we were told by our TV to sync a phone or tablet, connected to our home's Xfinity Internet connection, to our box. The approved list during the beta included most iPad models and many Samsung phones and tablets but no other brands' devices.
This limitation wasn't due to any app installation. Instead, the Xfinity Games app asks users to load a website and enter an authentication code, at which point the service's HTML5 interface pops up on a Web browser. We're not sure why Comcast has posted such a narrow "compatible" device list, but our attempts to run Xfinity Games’ companion HTML5 interface on an LG Nexus 6 resulted in more crashes and errors than on an iPad Air 1, so we stuck with their rules. (Users are also required to sync up a current or new EA Origin account.)

Games are quite quick to load, and gameplay appears exclusively on the TV screen. In other words, the mobile device's screen is dedicated to controls, and you'll see no live information or animation that corresponds with the game in question there. Only one game, PGA Tour, offers an elaborate touch-screen; the rest are incredibly simple interfaces that either offer virtual controller buttons or employ a mouse emulator.
[this sounds inferior to the Beach Buggy Racing Nearby Connections API arrangement on Android TV]
If it just emulates a standard USB keyboard and mouse, like the website says, then there's no reason why it wouldn't work with the Shield.
But why not just use the official Android TV Remote app instead? The only thing you'll lose is the mouse emulation, which isn't useful unless you're sideloading apps.
