Earlier this year we had a use case aiming at OSM data getting
'compiled' into Scenery for use with the OpenSource FlightGear flight
simulator ("Using OSM data in a computer game [...]").
This use case has meanwhile been transformed into a scenario that
doesn't apply to FlightGear any more as FlightGear, the source code as
well as the "Scenery" data is published under the GPL (v2). Thus the
resulting Scenery format is in no way neither proprietary nor closed -
in contrast to the scenario now expressed in the respective use case.

Should 'we' add yet another use case ? Another 'solution' that allows
'us' to implement OSM's road layout in FlightGear Scenery would be
indeed having a clause as proposed above added to the license.

Cheers,
	Martin.
