There are three classes of remotes.. Fixed function - the device is hardwired Universal - you can change the device Multi-function - a universal that can be multiple devices - TV, cable, audio, etc If you set two Bluetooth remotes both to the same device you can't tell them apart either. Two identical fixed function remotes can be distinguished and they shouldn't be distinguishable. To distinguish between universal remotes just change the device being emulated. > > So yes, keymapping is the same, but that's pretty much it.
