Is Quartz Pixar’s Renderman’s lost cousin?

I was watching a video introduction to NeXTSTEP 3 by Steve Jobs and Steve Jobs said that NeXTSTEP had Renderman included in it, and an “interactive” Renderman.

So what do you think? Is Quartz Renderman’s lost cousin? Seeing as that Pixar has always used Steve’s platform, it very well may be.
