Just to throw an extra spanner in the discussion – darcs (the original DVCS) 
solves the above problem by regarding repositories as sets of patches instead 
of as lists of states, which allows you to take patches from any repository and 
push them into any other repository (given some constraints).  This means you 
can do away with the idea of an "authoritative" repo, and happily push changes 
between each other without issue.
