Regarding the copyright and IP - interesting I have been speaking with someone regarding this as they are in the process of setting up development team.
One of the interesting things I learnt was
http://www.bistudio.com/ at the start of ARAM2 have a disclaimer regarding weapons, vehicles, and aircraft within in and it's legal as long as you do not use copyright and trademark names.
C-130J interestingly enough is in fact copyrighted...
