DDJ-RZX Rerkordbox License question

Hello!

I just pre-ordered a RZX from a local distributor.  However, I have a question.

I understand the RZX cames with ONE rekordbox license.

Since the device has two usb ports, I would use it with a friend, who doesn't own rekordbox dj license.

How is this going to work?  Rekordbox will get activated when the hardware is plugged in?  (kind of like serato does)  Do I have to share the license with my friend?  Does my friend need to buy a license?

Thank you
