It uses the same software, but you can't really copy any settings over. About the closest thing you could do would be to login to your account and then plug in her remote. Hit the update button and it should come up with a screen that says that it is a different remote and it gives you the option to either change your setup for the new remote, or copy your settings to a new account for the new remote. Use the copy option and set up a new account for her remote.
Be aware if this screen doesn't come up, or if you accidently pick the wrong selection it will screw up a lot of your settings (custom button mappings) and you will have to redo-them.
You aren't going to try to use these both in the same room are you? That usually doesn't work out well because they can't keep track of the state of all of the devices correctly.
