So I came across this program, it's kind of like a P2P network like Limewire, but the stuff you choose to share is only available to people you add as contacts. You can choose what folders you want to share and even exclude certain files if you wish.
So all you do is download the program ( http://www.gigatribe.com/
) and make an account, then start adding contacts who you wish to share with. Check it out.
