Everything we know so far: Vector IS going to have an unlockable bootloader! We don't have anything completely concrete yet, but this is how we plan to do this. Like a phone, there will be a bootloader unlock program. Once unlocked, the userdata partition will be erased, and he would be untethered from the Anki/DDL account. So basically, you will be on your own. After unlock, you can update him via any address you want. You will not be able to get any SDK certificate (or any certificate) from Anki/DDL's servers (the team there will need to implemenet that). This way, no private key needs to be released. If you want to revert, we may let you do that with a user-driven factory reset. Stay tuned!
