Hey man,
regarding Mibii... it seem more like a brandable name than a way to make money off men in black II..... if you were to develop it that way you would probably be embarking on Trademark issues as well with the film..... your best bet is to make it your own since it does have a nice ring off the tounge.... but as for reseller value i'd say its probably just worth reg fee.... maybe in time though more..... all depends on if someone wants it...
Good luck!
