How far does the hub blast IR? I'm trying to figure out if the Harmony Ultimate will be a good solution for me. I have a projector hanging from the ceiling about 15 feet from my equipment (where the hub would go). Will this be able to turn on/off my projector? Also, if the hub is inside the av cabinet, will it blast IR to all components in the cabinet or does it need direct line of sight? If it needs direct, it seems tough to position the hub to blast to multiple components unless I'm missing something.
