[OSM-talk] What the license change is going to do to the map

[Josh Doe]

I would like to say that I'm surprised no one has created a tool yet
to simulate what a given area would look like after the switchover
given the current (or simulated) list of users that have agreed to the
new terms. It would take as inputs an .osm file and users_agreed.txt
[1], and then apply the logic from [2] to create a new .osm with all
"offending" data removed. Or maybe the .osm doesn't contain the
history, so it would rather take a bounding box and then use the API,
I'm not sure. Clearly I don't have the skills or knowledge to create
this tool, but I hope someone takes the task!
