the solution would probably be a portable dev server that is modified to
do syncing/conflict check - then you could download just conflicting
nodes (and region) in josm, resolve them, upload and wait for sync with
the OSM-master

of course this solution is purely theoretical but the code exists for
dev server and conflict checking (which'd need to be ported from java to
ruby) and add a new interface for a conflict-bbox (get all conflicts
with 1km radius (or square for simplicity) within x1y1:x2y2)

would be useful for mapping parties, too.
