I think that the six paths Tobi mentioned are six seperate bloodline limits in the shinobi world, which, when combined, give one the powers of the original Sage (minus the Juubi). If his powers divided once they could divide again after all. This would mean there are three dojutsu, and three 'body' bloodline limits, and hey ho the only three known dojutsu in the series (that I'm aware of) are the Rinnegan, the Sharingan and the Byakugan. Whilst the Byakugan's significance has only seemed to decrease since its introduction, it was mentioned by Kakashi - I think when Neji fought Hinata, that it was the predecessor to the Sharingan, and Kishimoto has shown us repeatedly that little details always come back at some point. As for the other three, I think the longevity of the Uzumaki must be one, and possibly the mokuton from the Senju clan, which like the Sharingan might only expresses itself in certain members. The final path... who knows? There's a strong parallel between Uchiha and Senju, the Uzumaki clan were described as a branch of the Senju clan, and the Hyuuga are supposedly related - at least through their eyes - with the Uchiha. Chapter 520 would indicate there was only ever one Rinnegan, the Sage's, so perhaps the last path is also something that was unique to the Sage (maybe Kabuto literally has the Sage's body lol)
