I've been running into this problem while working through marketing docs/accelerator apps/etc. with a new startup. There's still a huge hole in collaborative document editing. Tools are either too simple to do this well (thinking of hackpad) or too complicated for quick uses (editing mode in word/comments in google docs). An elegant solution for this kind of back-and-forth editing dialog on short-form copy would be huge. Surprised it doesn't exist already. And the concept of one-click "commits" is a powerful one for versioning -- makes it much easier to find things than google's atomic "save everything" version control. Nice work. Look forward to giving this a try.
