Speaking of Mormons, there was a television documentary recently that did an in depth study of ritualized multiple attachments amongst Mormons. I didn't see the very beginning so I'm not sure whether this was an offshoot or if it could be considered mainstream Mormonism.

The approach was respectful and the couples (*g*) responded freely. According to them, they got around the legalities by having only one 'wife'; the others were 'sister wives'.

It was interesting.
