I've got a copy of planet.osm.pbf and a subsection op_area.osm (bounded by bounds.poly) which covers several US states. I've also set up a way to get the planet.osm diffs each week (rssdownloader + rtorrent + http://osm-torrent.torres.voyager.hr/files/rss.xml, for the curious), and it's trivial to automatically apply the diff to planet.osm.pbf and write out an updated version. Then I can clip the planet whichever way I want, and write a new op_area.osm. The problem is, clipping the planet after applying a changeset takes ~6 hours with my current hardware. Is it possible to apply the planet-based diffs to op_area.osm using osmosis (or some other tool) without needing that intermediate step?step? I couldn't find any pipeline items that can take a change stream and apply bounds.
