Well, I had some thought on Kurama used as a summoning creature, and several question arose which I'd like do discuss. It all revolves around the unusual mechanics of this case.
 * Firstly, Kurama isn't an actual summoning animal, as we know. All the usual summonings live in their separate plane and it's necessary to sign a contract with them for the summoning. Kurama neither has a separate plane nor a summoning contract. So, how Madara/Obito made it possible to summon him?
 * Secondly, one of the traits of the summoning technique is a time limit, i.e. the summoning can stay with the summoner only for the limited amount of time, and then it returns to his own home. And Obito mentioned the same trait for the Kurama (the time limit of the Nine-Tails summoning). Yet, how does it work? Again, Kurama has no home to return to, what would happen if the time was over?
 * Thirdly, it seems that Madara kept that contract with Kurama, since he tried to summon him during the battle with Fourth Division to check out the situation. The summon failed due to Kurama residing inside Naruto. But as we also know, the Kurama within Naruto was just a half of the actual one, while Madara used a complete Kurama as his summoning. So, what do you thing would happen if both Yin and Yang Kurama were roaming free, and Madara tried to use the summon? Would both be summoned at the same time, only one of them, or the summoning would merge them into the single entity again?
