JOSM Public startup option

[pierzen]

Using JOSM with sharable computers in a classroom, the preference file keeps the information about the openstreetmap account. This do not assure OSM database integrety. Also, the trainers cannot follow-up easily the trainees activities (ie, who is logged, daily statistics, etc.).

A Public option at startup of JOSM would take care of this and wouold have the effect to erase openstreetmap account information.

You should use an own account for each user. Everything else is insecure.

If you do not want to follow this security instruction you could still use a different JOSM preference directory for each user with the java command line option -Djosm.home="path" or reset the preferences to defaults with JOSM command line option --reset-preferences (untested). See command line option.

Within JOSM you still can use an option with OAuth to only use the token for the current session and not to save it to preferences.

By the way, you should always use OAuth as passing you credentials to the OSM-Server unencrypted is insecure.

Think you have many options.
