One set of headphones per person?

I can sit in dozens / hundreds of different seats in a well-designed movie theatre and enjoy very good sound, regardless of the number of people in the theatre. In fact part of the attraction of going to a theatre is that it is a shared, rather than solitary, experience. I see no reason why the principles used in such a large application cannot be scaled down such that several people can enjoy very good sound in a home theatre. I don't buy into the "lone-listener gets the sweet spot" approach. Nor would I ever want to turn this hobby into anything other than a shared experience.
