Recently Etherpad added the Timeline feature to their webapp, and while looking at it, I had thought maybe this could be applied as a version control method. There would be a timeline for each file in a project and all changes to that file would get recorded to the timeline. When you hit checkin, a bookmark appears in the timeline. This could probably only be implemented as a full fledged text editor.

The key idea behind this is that you don't really have to bother about version control at all, since the software automatically records everything to the timeline.

So would any of you be interested in such a software, if anybody were to develop it??? Depending on your answers, I may put some work into it.
