Well, I had some thoughts on Kurama used as a summoning creature, and several questions 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 own separate plane and it's necessary to sign a contract with them for the summoning. Kurama has neither 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 Minato mentioned the same trait for Kurama (the time limit of Tobi's Nine-Tails summoning). Yet, how does it work? Again, Kurama has no home to return to, what would happen when 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 would the summoning merge them into the single entity again?
