Apple doesn't have predictable serial numbers anymore, they're all just random numbers corresponding to rows in a database. There's no way to generate them.
It wasn't a serious idea. The fact I mentioned it along side Serial Box should have been a clue. Maybe you're too young to know what Serial Box was, or the 90s cracking culture. Shh, the adults are speaking =)
You have to de-register the device with Apple when you sell it. Otherwise you retain the ability to remote wipe and brick the device and the buyer has no recourse.
After you de-register it the buyer can register it with Apple under their Apple ID.
I have Apple devices that are allowed to use iMessage including some that I don't use. If my computer can impersonate one of them to allow me to message from my workstation that's success.

But Beeper Mini isn't asking users to bring-their-own valid hardware registered Apple hardware ID tied to their Apple ID, they're doing something different/unknown behind the scenes
oh wait. i drifted off back to the 90s software cracking days.
