I am sure there are as many ways to go about polyandry as there are ways to have the relationship itself. It's different for everyone.
I think integration is key. If everyone can't get along and bring something to the table of life, then it'll never work out. We all need to have jobs, daily life roles - errands, routine, responsibilities...
I find people who are open, honest and don't worry about the consequences of that make wonderful people. You can work with that any day of the week when you have a pure intentions heart like mine.
