Hi Coz, I can't add much to what everyone else has said in this thread. The OSG is compatible with GPL'd apps. You can also create your own code that extends the OSG that is GPL'd. The LGPL does premit you to distribute under GPL as well so again you can do this. However, it does effectively bar you changes form being merged with the OSG as I'm not going to merge changes that change code that is OSGPL/LGPL to GPL as it would preclude the use of the OSG by the majority of it's user base. This would mean you'll have to maintain a branch of the code yourself. Frankly this would be a bit dumb, licensing under the OSGPL/LGPL would not curtail your own usage of your codes and it would enable your changes if deemed appropriate to be merged in to the core OSG and matinained/improved by the rest of the OSG community.
