Well Naruto's father had at least one S-class (I assume that level) space-time jutsu, so Naruto will probably learn a variant or learn to create his own.

The invincibility due to it reflecting all attacks we've seen is curious, and I wonder if it's like a barrier. Whereby if the opponent can get inside some area that is a blind spot to the jutsu. Not sure, since Itachi was walking towards Sasuke and the attacks were still being deflected. It may be the point of origin of the summoning is a blind spot. I know the shield reflects attacks, but it didn't push Sasuke's body.
Regarding Ameratsu, do you think it's possible for Jiraiya to turn his scroll that sealed away the black fire into hand-signs that could be formed? We know Ameratsu doesn't kill instantly, so I also wonder if Jiraiya could've made a seal on paper like he did for Naruto's leaking Kyuubi chakra.
No matter what these jutsus are, they didn't exist before they were made, or precursors, by the great Ninja Sage, whatever the name, who had the Rinnegan. That which is created can be destroyed in general.
I like these discussions quite a bit because I love problem solving. We are basically trying to do what someone who was going to fight the Sharingan would be doing like Kakashi or pervy Sage. I wonder if Minato developed a perverted jutsu since he was under Jiraiya. Flying Thunder Harem.
