I have, but I didn't know them that well. It was a married couple, and they even led a polyamory group. They seemed very happy.
I will admit that what I said before is all theory, not experience from practice. When I see poly people on the dating sites, they're way too "out there" for me to have any interest in them.
I have read though that there are successful poly relationships, and that relationship counselors generally agree that the successful ones have the best communication skills of all their clients. All the stuff I've read from them highly emphasizes communication skills.
