#2 in my case as we typically hunt together and most of our favorite spots were found while scouting together.
I really only hunt with three people including my wife. Our scouting, spots, and success/failure is an open book between us, but hunting with either friend is seperate (one is midwest based hunting while the other is western based). Both people are my closest friends and have been for well over 10 years. If either person ever wanted to bring someone else out such as friend or even their own family they would ask first just as I would if I wanted to bring someone new. Last year my one buddy wouldn't go out to our spots, even with the ideal conditions, because I was coming back to hunt in a week and he didn't want to burn the area. I told him multiple times to go out there, but he never did. It's not uncommon for us to argue with each other trying to get the other person to go to the better spot. He'd rather see me get a shot and I'd rather see him get a shot. I don't think we would ever let another local person hunt with us. We just have too much time and too many miles devoted to the areas we like to hunt.
In general I would trade my own valuable information (not something I scouted/hunted with a friend) in an out of state area for information that is valuable to me. That being said I have only done this twice. In both cases they were people I have never met in person. I've only used one person's information so far and I won't pass it on to anyone since they are still applying for that hunt/it isn't mine to share. I hope someday they will use the information I gave them.
