Wait, who says that it can only control the Jubi? I was under the impression that it worked on any biju. I mean, I don't suppose there were really any cases where this was shown one way or another, but I thought Madara had a level of dominance much like Hashirama's.
Only Hashirama had control over all the beasts, but Madara only had control over the Kyuubi. That, or I'm wrong and Hashirama had just better control over all the beasts. But there is a connection between Madara and the Kyuubi...and we do not know the full story, yet. (we know part of it)
I suspect that the Rinnigan could control any of them...which MAY be part why the Kyubi was rage-fitting about Madara trying to control him: he knows "Tobi" already has most of the others?
