Great idea, thank you!
The TV in question is approximately 40" (so there isn't a great deal of available concealment) and located near the top of the wall, in the Kitchen. The wall it's located on is made out of brick, but the brick ends a couple of feet above where the TV is mounted. I've been tempted to run an Ethernet line in the attic, and then simply conceal the Ethernet cable for those couple of feet down from where I'd pop a keystone into the wall (from the attic).
That line of thinking made me want to move the TV up even higher to cover the potential keystone, but like your idea. I'll look for something small that is supported by LEDE.
I'm pretty sure it does, but would you happen to know if the latest case made by FLIRC will fit the LP? I thought it would be neat to get the one with the KODI logo treatment, but I can't quite find a definitive answer anywhere. As much as I like the idea of getting a case with a fan, the ones listed that "officially" support the LP are not as aesthetically pleasing to me as the cases made by FLIRC.
