you responded to yourself...)

No, this is definitely *not* the case with darcs.  (Although it is how arch
works...)  There most certainly can be any number of changes that would go
between two identical repositories.  The replace patch is the obvious
instance, since any replace patch on any given file can be replaced by a
number of hunk patches.  Also mv patches violate this, unless you add to
your definition of "different" repositories a notion of file identity.
