Representing documents as [branching] lists of sequential diffs gets into really complex areas
like Operational Transforms[1] and Patch Theory[2]. Which are quite fascinating, and necessary
if you want to implement a version control system or Google Wave, but orders of magnitude
harder to implement than simply merging together two conflicting versions of a document according
to your application schema.
