Yes, other folks have brought up this idea, and I myself was looking into it when I started this project. To be completely honest, though, it is quite possible that none of the keysets currently in Pierogi will work with your TV; this code is still in development, and still has huge gaps in its internal database. (Not to mention that it is still undergoing testing.)

My plans are still to concentrate on getting a more complete, functional, and efficient back-end system running before adding this sort of feature. (In particular, if your TV didn't mute, it'd be hard to tell if it was due to a bug in Pierogi or due to the fact that Pierogi just didn't have the right keyset yet...)
