It would be really nice to add some JOSM layer functionality like this.
I did a simple shp-to-osm, then mucked with JOSM's style files a bit to
get it to show the background (new data) in pink and the foreground
(existing OSM data) in a thick line.  It makes isolating data that's
badly lined up or non-existent in OSM easy to find, visually.

In the US?  There were a couple of duplicate TIGER counties uploaded
that I would say were from people jumping the gun a bit, but I haven't
been aware of any more.  Any examples?
