Question/idea about multiple developers committing to one branch

[Nicholas Allen]

Perhaps this could be generalized so you could do this even without a 
smart server. So if bzr could store something in the .bzr directory that 
indicated that a branch's revisions should never change order then when 
you merge from a branch that has this property it would be your local 
branch's revisions that are reordered. This could then work for branches 
published via dumb file protocols as well. Is that possible?
