Roger Rosner, one of the founders of Lighthouse (before Jonathan Schwartz was in the company), now bears the title "VP iWork", and gave the demo of "Pages in the Cloud" for the WWDC keynote. Roger's demo starts at minute 92 in the keynote, http://developer.apple.com/videos/wwdc/2011/ .

So yeah, Jobs seems particularly interested in the relationship of NeXT, Lighthouse, and iWork/Keynote.
