I am 100% in on making this. Another recent thread where I chimed in on making something with fewer buttons. I also lament about the latest LG offerings. I even propose ditching a first party remote in favor of just connecting with your favorite one. Why add to the problem of too many remotes by adding yet another one?

I would love to chat with someone who knows more about the hardware side. How do you get a panel with a "dev kit" where you can load on the copy protection and all the modern stuff needed to play DRM content? I would be up for building a new OS from scratch.
