I'm not a lawyer & might not be the best person to advice you and your friend. There is a heck a lot of difference with understanding theoretically (even that very limited) and its use practically. Suggest you speak to a lawyer.
A humble request.. Next time if you see ajtr post, please restrain from any posting and let the post die its natural death. If we post anything into it, he gains undue importance. Ignore the post and move on. This is what i have been doing and fairly successful.
