This is awesome work. Well done, Dave.
Now that they're officially out of the handheld controller game, I hope Lionel takes notice and really open things up with Legacy to allow 3rd parties to bring their own control hardware, and even actively support integration with Base3 and a lot of the other stuff they make. This is a great way to get technically minded folks into the hobby, too. I don't really see how it could hurt them unless they ever change their mind about making hardware remotes, but even then, most people would probably just buy theirs again anyway.
