Yeah I was pretty excited when I tripped over that single IR code. We were in the middle of a pretty large Sonos install when the customer wanted to add local TV sound to a few rooms...it really saved my ass. Nice thing is it works every single time. Ive even been using IR for volume control lately and only relying on the volatile Crestron module for FB and basic control. This way ensures than WHEN the module fails the customer can still watch TV and control the volume.
