Another thought on Subversion as a changeset engine

It has occured to me that Subversion is already "almost" a changeset database, as the "deltas" it stores are equivalent to changesets---only they are reversed (i.e. they create the preceeding version from the following one, instead of the other way around).
Now, if we could just create an algorithm for reversing deltas, Subversion can become a "real" changeset database without almost any change in the existing semantics.
Is this possible? Or are deltas fundamentally irreversible? (I do recall something was said about it on the list once, but I can't remember what... And couldn't find it in the archives :-( )
