The other answers are correct about only needing a single peer among any pair of peers to be addressable.
However there is a built-in hole punching mechanism in BitTorrent where peers ask for a third peer to assist in hole punching.
It's implemented in my client. It was very painful to implement. I think someone privately funded the feature which was very nice.
