You will need to apply the full diffs and afterwards cut off anything 
you're not interested in.

If you intend to do it for a rather small area then it is really quite 
easy and performs well with Osmosis. Assuming you have a current extract 
of your area in "current.osm" and you have the Osmosis replication set 
up properly (--rrii), then you simply run

osmosis --rri --simc --rx current.osm --ac --bb <boundingbox here> 
clipIncompleteEntities=yes --wx new.osm && mv new.osm current.osm

as often as you like. The <boundingbox here> has to be replaced by a set 
of "left=x right=x top=x bottom=x" where you specify the section you are 
interested in.

Bye
Frederik
