Hi guys. I'm a developer of payware add-ons for X-Plane and have been hearing some buzz about FlightGear. One thing that caught my attention is that FlightGear is built on top of OpenSceneGraph and osgEarth, and my company's technology for volumetric clouds, skies, and 3D water effects integrates really easily into those sorts of systems. (See http://www.sundog-soft.com/ if you're curious.)
The problem is that this technology is not free and open source, but FlightGear is. So, a few questions before I explore things further:
1. FlightGear is under a GPL license, which means any add-ons that it links in must also be GPL (open source.) Payware for FG is a non-starter, unless a modified license to carve out add-ons has been discussed. Has it, to anyone's knowledge?
2. Hypothetically speaking - would you pay for an add-on to a free product if it were good enough? My main concern is that users of a free / open source simulator could have an allergic reaction to add-ons that are not.
3. Anyone have an estimate of the relative percentage of Linux / PC / Mac users of FG?
