Wassup? Where did the project go, is it stalled, being worked on furiously in secret?

I'm too busy until some time in 2007 to do other than indulge myself with an occasional peek but there's a lot of synergy between this project and other stuff I've been working on and thinking about with regards to storing and choosing variants of bits of a rich document.

Some thoughts so far:
1) I think settling on a version-control system as a backend is a huge rathole down which the entire project will disappear. The semantics of file-oriented revision control are not what you're discussing. In particular, you want more incoherent merging, picking bits out of a set of changes.

2) I am playing with a tablet (I know, we're all still waiting for iTablet). These things are made for editing!
