Yeah but how come the George Bush Presidential Library had to buy their domain name from someone. George Bush has a right to his name
Heh, that was actually a lucky one-shot deal. The Bush library could actually have taken legal action...if they knew about it back then. Maybe you'll get lucky, maybe you won't. Up to you if you want to play.
If you are unsure about anything then it's usually best to get the permission upfront... don't despair, if they don't give permission on the initial idea. Keep coming up w/ some ideas and repeat the process to obtain permission... they'll be tired of rejecting you too many times then you have some thing to work with...
