You have bashed the Roku because it interferes with your router (mine does not interfere with mine at all). You have bashed the Fire TV because it won't accept IR because you are "heavily invested in IR"...Hardly, You just want to use the Sony remote is all, but unwilling to spend $14. Hey man, no skin off my nose. Everything works fabulously here and I don't use an IR remote, I use a BT remote.
But, whatever floats your boat. I wish you luck in finding what you are searching for.
