Thanks Robert, that's a sound justification. I know many of us have had discussions with the wider OSM community about the merits of remote mapping and the impact this may have on local groups.
I'm pleased to see the discussion here and hope there are solutions that benefit both mappers, aid orgs and the OSM ecosystem.
