[OSM-dev] Whole-planet JOSM

I'd like to be able to take my laptop connected to a GPS on a trip
across the country and browse and edit map data without an internet
connection until I get home.

Currently, as the number of nodes loaded into JOSM increases, it gets
less and less responsive. Has anyone thought about changing JOSM to use
a local DB and be able to load a whole planet file? Downloading an area
with the download button would then just update that area in the local DB.

The other thing that would be needed is on upload, it would need to
download small areas around what you have changed to check for
conflicts. Obviously, if I have changed one node in the UK and another
in Australia, I don't need to download everything in between, only the
nodes around each edit.

Thanks,

Robert (Jamie) Munro
