Well uhhh... the goal was sort of.. to.... uhhh....
Also note that you can't actually transfer into slime people, as they do not have an area for a brain, positronic or otherwise.
EDIT: In addition, wouldn't locking it to be players who have the race unlocked or start as the race sort of be redundant ,as most of the time you'll only actually be able to utilize this when the body is completely and totally destroyed, yet the brain is still intact, which rarely, if ever, happens enough for it to be a reasonable cause for allowing robotics to construct such a piece of equipment? Not sure if it'd be any different than just joining as the race and trying to not die.
