Actually they can be an exact copy. The OP said he chooses the floor then the display then the source. A pain in the ass on 900's but there's no reason they can't all be exactly the same. It all depends on how you configure them. The reason for this is if 1 dies, the customer can then grab any other remote and watch wherever he wants. It also makes upgrading much easier as you're only writing 1 remote file.
